bors 0b24479638 Auto merge of #116555 - paulmenage:llvm-module-flag, r=wesleywiser 
Add -Z llvm_module_flag

Allow adding values to the `!llvm.module.flags` metadata for a generated module.  The syntax is

`-Z llvm_module_flag=<name>:<type>:<value>:<behavior>`

Currently only u32 values are supported but the type is required to be specified for forward compatibility.  The `behavior` element must match one of the named LLVM metadata behaviors.viors.

This flag is expected to be perma-unstable.

README.md

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
