This check wasn't very useful and removing it simplifies the code.
This ensures that all stack slots are aligned to 16 bytes. Without this linking against crates compiled with cg_llvm may cause a crash due to simd instructions requiring a 16 byte alignment.

This fixes several cases of crashes when interfacing with C code. In addition this will make it possible to build dependencies using cg_llvm with optimizations and only build the user program using cg_clif. While I haven't yet added support to the build system for this, I have manually confirmed that building simple-raytracer against the cg_llvm sysroot works. (albeit resulting in a somewhat slower executable for some reason) I have also confirmed that linking bevymark against a cg_llvm compiled bevy works.
Fixes https://github.com/bjorn3/rustc_codegen_cranelift/issues/10. This is the oldest currently open issue and the last open issue I assigned to the MVP milestone back in August 2018.
