65925b04 - [AMDGPU] Replace AMDGPUISD::FFBH_I32 with ISD::CTLS (#178420)

[AMDGPU] Replace AMDGPUISD::FFBH_I32 with ISD::CTLS (#178420) Per CDNA4 ISA: V_FFBH_I32 Count the number of leading bits that are the same as the sign bit of a vector input and store the result into a vector register. Store -1 if all input bits are the same. which matches CTLS semantics. Addresses: https://github.com/llvm/llvm-project/issues/177635
