ipa-sra: Avoid transitive splits with type mismatches (PR 96040)
PR 96040 revealed IPA-SRA, when checking whether an intended split is
the same as the one in a called function does not also check if the
types match and the transformation code does not handle any resulting
type mismatches. This patch simply avoids the the split in the case
of mismatches, so that we do not have to be careful about invalid
floating-point values being passed in floating point registers and
related issues.
