<summary>Changes</summary>

These are already the default calls set for these conversions, so
they should not require explicit setting. The non-default cases are
currently overridden in ARMISelLowering. Just delete this until
the list of calls and lowering decisions are separated.

This was added back in 6402ad27c01c9503a12d41d7e40646cf0d1f919f. It
appears to not be relevant for AArch64, where calls appear to never
be used for these. It also appears to not be relevant for x86, where
the default calls seem to always end up used anyway.
