e8e8d30b - [Hexagon] Use __HVX_IEEE_FP__ to guard protos that need -mhvx-ieee-fp (#184422)

[Hexagon] Use __HVX_IEEE_FP__ to guard protos that need -mhvx-ieee-fp (#184422) Hexagon clang recently started to define __HVX_IEEE_FP__ when the -mhvx-ieee-fp option is specified. Guard the intrinsic macros for instructions that should only be available with -mhvx-ieee-fp with __HVX_IEEE_FP__. Additionally, the following NFC changes are included: - NFC: Remove guards around HVX v60 intrinsic macros Hexagon v60 is the oldest Hexagon version that supports HVX so these guards were redundant. Presence of HVX is guarded separately, once per the whole file. - Remove comments from closing guards (HVX protos) These comments served very limited function as they only guard one macro. Also, they were incorrect. Instead of fixing remove them. This will also reduce by the factor of two the amount of changes when guarding conditions change.
