Add support to CodeGen_LLVM for generating architecture specific assertions. #8092

Open zvookin opened 9 months ago

CodeGen_ARM, for SVE, generates a runtime check that the current processor supports the vector length compiled for. This is done in begin_func by checking if the current function does not have internal linkage. Adding a specific method to accomplisht his would be cleaner.

I suspect the thing to do is override compile(Module) in CodeGen_ARM to run an inject-assertions IRMutator on the right LoweredFunc, and then call the base class method. Or maybe override compile(LoweredFunc) and just mutate the ones with an external linkage type
