855443d4 - [RuntimeLibcalls] Use a multiclass for all libm impls (NFC) (#148349)

[RuntimeLibcalls] Use a multiclass for all libm impls (NFC) (#148349) `LibmLongDoubleLibcalls` currently handles generating definitions for the three long double variants, but `F32` and `F64` always get a written definition. Simplify this by changing `LibmLongDoubleLibcalls` to `LibmLibcallImpls` that also expands `F32` and `F64`. As part of this, `LibmLibcallImpls` can take a function name with an `X` placeholder, to be replaced with the float type suffix. This allows the multiclass to also be used for libcalls with the suffix in the middle rather than strictly at the end.
