Help wanted with fixing misspelled FileCheck directives

There’s been published a patch recently making FileCheck to catch misspelled directives:

https://reviews.llvm.org/D125604

Being as useful as large is the amount of misspelled directives discovered, some of the fixes, marked TODO, are not very trivial and likely require attention of corresponding teams and individuals:

clang/test/CodeGen/cmse-clear-return.c
llvm/test/CodeGen/AArch64/fp16-v8-instructions.ll
llvm/test/CodeGen/AArch64/neon-vmull-high-p64.ll
llvm/test/CodeGen/AMDGPU/phi-vgpr-input-moveimm.mir

Will you have a chance, please take a look and let me know so we don’t duplicate efforts. Thanks!
