RFC: Adding argument allocas
Clang is currently missing some low-hanging performance and code size
opportunities when receiving function parameters. For most scalar
parameters, Clang typically emits an alloca and stores the LLVM SSA
argument value into the alloca to initialize it. With optimizations, this
initialization is often removed, but it stays behind in debug builds and
when the user takes the address of a parameter (
