[llvm-branch-commits] [SPARC][IAS] Handle the case of non-4-byte aligned writeNopData (PR #94251)

[via llvm-branch-commits]

If the Count passed into writeNopData is not a multiple of four,
add a little amount of zeros before writing the NOP stream.
This makes it match the behavior of GNU binutils.
