Revert "[AArch64] Enable subreg liveness tracking by default."
This reverts commit 9c319d5bb40785c969d2af76535ca62448dfafa7.
Some issues were discovered with the bootstrap builds, which
seem like they were caused by this commit. I'm reverting to investigate.

AArch64: Add FMINNUM_IEEE and FMAXNUM_IEEE support (#107855)
FMINNM/FMAXNM instructions of AArch64 follow IEEE754-2008. We can use
them to canonicalize a floating point number. And
FMINNUM_IEEE/FMAXNUM_IEEE is used by something like expanding
FMINIMUMNUM/FMAXIMUMNUM, so let's define them.
Update combine_andor_with_cmps.ll.
Add fp-maximumnum-minimumnum.ll, with nnan testcases only.
V1F64 is not supported yet.
If we set v1f64 as legal, FMINNUM/FMAXNUM will have some problem:
both of them use `if (isOperationLegalOrCustom(FMAXNUM_IEEE, VT))`.
AArch64 depends on `expandFMINNUM_FMAXNUM` returning `SDValue()`
for FMAXNUM and FMINNUM.
We should fix this problem, while it will be in future patch.
