fb77604e79 Add the weak-intrinsics feature 
When enabled, the weak-intrinsics feature will cause all intrinsics
functions to be marked with weak linkage (i.e. `#[linkage = "weak"])
so that they can be replaced at link time by a stronger symbol.

This can be set to use C++ intrinsics from the compiler-rt library,
as it will avoid Rust's implementation replacing the compiler-rt
implementation as long as the compiler-rt symbols are linked as
strong symbols. Typically this requires the compiler-rt library to
be explicitly specified in the link command.

Addresses https://github.com/rust-lang/compiler-builtins/issues/525.

Without weak-intrinsics, from nm:
```
00000000 W __aeabi_memclr8  // Is explicitly weak
00000000 T __udivsi3  // Is not.
```

With weak-intrinsics, from nm:
```
00000000 W __aeabi_memclr8  // Is explicitly weak
00000000 W __udivsi3  // Is weak due to weak-intrinsics
```

fix: Add #[avr_skip] for bit shifts 
This commit follows the same logic as:

- https://github.com/rust-lang/compiler-builtins/pull/462
- https://github.com/rust-lang/compiler-builtins/pull/466

I've tested the changes by preparing a simple program:

```rust
fn calc() -> ... {
    let x = hint::black_box(4u...); // 4u8, 4u16, 4u32, 4u64, 4u128 + signed
    let y = hint::black_box(1u32);

    // x >> y
    // x << y
}

fn main() -> ! {
    let dp = arduino_hal::Peripherals::take().unwrap();
    let pins = arduino_hal::pins!(dp);
    let mut serial = arduino_hal::default_serial!(dp, pins, 57600);

    for b in calc().to_le_bytes() {
        _ = ufmt::uwrite!(&mut serial, "{} ", b);
    }

    _ = ufmt::uwriteln!(&mut serial, "");

    loop {
        //
    }
}
```

... switching types & operators in `calc()`, and observing the results;
what I ended up with was:

```
 u32 << u32 - ok
 u64 << u32 - ok
u128 << u32 - error (undefined reference to `__ashlti3')
 i32 >> u32 - ok
 i64 >> u32 - ok
i128 >> u32 - error (undefined reference to `__ashrti3')
 u32 >> u32 - ok
 u64 >> u32 - ok
u128 >> u32 - error (undefined reference to `__lshrti3')

(where "ok" = compiles and returns correct results)
```

As with multiplication and division, so do in here 128-bit operations
not work, because avr-gcc's standard library doesn't provide them (at
the same time, requiring that specific calling convention, making it
pretty difficult for compiler-builtins to jump in).

I think 128-bit operations non-working on an 8-bit controller is an
acceptable trade-off - 😇 - and so the entire fix in here is
just about skipping those functions.

ebaca42a41 Use a stub stdlib.h when compiling for UEFI targets 
int_util.c includes stdlib.h if `_WIN32` is defined. When compiling
the UEFI targets with clang they are treated as Windows targets (e.g. if
the Rust target is x86_64-unknown-uefi, the clang target is
x86_64-unknown-windows-gnu). So stdlib.h gets included, even though we
are compilling with `-ffreestanding` and don't want stdlib.h to be
used. That file may not be present, or an incompatible version might be
installed leading to typedef redefinition errors.

The contents of stdlib.h aren't actually needed for these targets anyway
(due to `__STDC_HOSTED__` being 0), so create a minimal stdlib.h in
`build.rs` when `target_os == uefi` and add it to the include path.

98b3454d3d Skip assembly implementations on the UEFI targets 
The UEFI targets link with `/SAFESEH`. That requires that objects have a
symbol called [`@feat.00`]. Clang adds that symbol for COFF targets if
the input is a C file, but not if the input is an ASM file. That doesn't
prevent compiler_builtins or rustc from building, but using the
resulting rustc to compile something that references one of the objects
lacking `@feat.00` will result in a linker error.

Fix by removing all the `.S` implementations when `target_os == uefi`.

[`@feat.00`]: https://learn.microsoft.com/en-us/windows/win32/debug/pe-format#the-sxdata-section

abb6893a85 Enable unadjusted_on_win64 for UEFI in some cases 
The conversion functions from i128/u128 to f32/f64 have the
`unadjusted_on_win64` attribute, but it is disabled starting with
LLVM14. This seems to be the correct thing to do for Win64, but for some
reason x86_64-unknown-uefi is different, despite generally using the
same ABI as Win64.

bb0b7d660f build: compile C code for "xous" operating system 
The "xous" operating system is enturely Rust-based, meaning it has no
libc. Therefore, it relies on `compiler-builtins` for all intrinsics.

Unfortunately, there are not yet Rust equivalents for all C functions.
For example, triganometric functions are still missing. In the meantime,
enable C replacements for these functions so that Rust programs compiled
for Xous can call these functions.

Fix division on AVRs 
For division and modulo, AVR uses a custom calling convention that does
not match compiler_builtins' expectations, leading to non-working code¹.

Ideally we'd just use hand-written naked functions (as, afair, ARM
does), but that's a lot of code to port², so hopefully we'll be able to
do it gradually later.

For the time being, I'd suggest not compiling problematic functions for
AVR target - this causes avr-gcc (which is a mandatory part of Rust+AVR
toolchain anyway) to link hand-written assembly from libgcc, which is
confirmed to work.

I've tested the code locally on simavr and the patch seems to be working
correctly :-)

7d79662fd1 Remove apple_versioning.c inclusion 
According to the README this file isn't used by rust, but it's currently
included which leads to these linker warnings in some cases:

```
ld: warning: linker symbol '$ld$hide$os10.5$___udivti3' hides a non-existent symbol '___udivti3'
ld: warning: linker symbol '$ld$hide$os10.4$___umoddi3' hides a non-existent symbol '___umoddi3'
ld: warning: linker symbol '$ld$hide$os10.5$___umoddi3' hides a non-existent symbol '___umoddi3'
ld: warning: linker symbol '$ld$hide$os10.4$___umodti3' hides a non-existent symbol '___umodti3'
ld: warning: linker symbol '$ld$hide$os10.5$___umodti3' hides a non-existent symbol '___umodti3'
```

This file exclusively contains macros which hides old symbols on Apple
OS versions where they don't exist.

0575846f80 Handle Win64 builtins ABI change in LLVM 14 
As of https://reviews.llvm.org/D110413, these no longer use the
unadjusted ABI (and use normal C ABI instead, passing i128
indirectly and returning it as <2 x i64>).

To support both LLVM 14 and older versions, rustc will expose a
"llvm14-builtins-abi" target feature, based on which
compiler-builtins can chose the appropriate ABI.

This is needed for rust-lang/rust#93577.

f03c7fd6af Wrap all intrinsics in the intrinsics! macro 
This ensures that each intrinsic ends up in a separate module, which in
turn (because rustc treats compiler_builtins specially) will result in
each intrinsic ending up in its own object file. This allows the linker
to only pick up object files for intrinsics that are missing and avoids
duplicate symbol definition errors.
