[AArch64] Use FMOVDr for clearing upper bits (#83107)
This adds some tablegen patterns for generating FMOVDr from concat(X,
zeroes), as the FMOV will implicitly zero the upper bits of the
register. An extra AArch64MIPeepholeOpt is needed to make sure we can
remove the FMOV in the same way we would remove the insert code.
