eaaa94318b Unpin cc and upgrade to the latest version 
`cc` was previously pinned because version 1.1.106 dropped support for
Visual Studio 12 (2013), and we wanted to decouple that from the rest of
the automated updates. As noted in [2], there is no longer anything
indicating we support VS2013, so it should be okay to unpin it.

`cc` 1.1.22 contains a fix that may help improve the high MSVC CI
failure rate [3], so we also have motivation to update to that point.

rustc_llvm: adapt to flattened CLI args in LLVM

This changed in
llvm/llvm-project@e190d074a0. I decided to stick with more duplication between the ifdef blocks to make the code easier to read for the next two years before we can plausibly drop LLVM 19.

Rollup merge of #130477 - tmandry:revert-llvm-20-lto, r=tmandry 
Revert #129749 to fix segfault in LLVM

This reverts commit 8c7a7e346b, reversing changes made to a00bd75b6c.

Reported in https://github.com/rust-lang/rust/pull/129749#issuecomment-2354417960. `@nikic's` theory is that the LLVM API changed in a way that makes it impossible to use concurrently from multiple threads (https://github.com/llvm/llvm-project/pull/106427#issuecomment-2354783802). I pinged `@krasimirgg` who was fine with reverting.

closes https://github.com/rust-lang/rust/issues/50156
cc https://github.com/rust-lang/rust/issues/49572 shall be fixed but not possible to see as there is asserts that already trigger the optimization.

6e9afb8dde Enable zstd for debug compression. 
Set LLVM_ENABLE_ZSTD alongside LLVM_ENABLE_ZLIB so that --compress-debug-sections=zstd is an option.
Use static linking to avoid a new runtime dependency. Add an llvm.libzstd bootstrap option for LLVM
with zstd. Set it off by default except for the dist builder. Handle llvm-config --system-libs output
that contains static libraries.

776b0adaaf Fix incorrect NDEBUG handling in LLVM bindings 
We currently compile our LLVM bindings using `-DNDEBUG` if
debuginfo for LLVM is disabled. However, `NDEBUG` doesn't have
any relation to debuginfo, it controls whether assertions are
enabled.

Rename the environment variable to `LLVM_ASSERTIONS` and drive
it using the `llvm_assertions` option. Also drop the explicit
`debug(false)` call, as cc already sets this up using the
cargo `DEBUG` environment variable.
