When we canonicalize the comparison for a czero sequence we need to handle both
integer and fp comparisons. Furthermore, within the integer space we want to
make sure we promote any sub-word objects to a full word.
All that is working fine. After promotion we then force the value into a
register if it is not a register or constant already. The idea is not to have
to special case subregs in subsequent code. This works fine except when we're
presented with a floating point object that would be a subword. (subreg:SF
(reg:SI)) on rv64 for example.
So this tightens up that force_reg step. Bootstapped and regression tested on
riscv64-linux-gnu and tested on riscv32-elf and riscv64-elf.
Pushing to the trunk after pre-commit verifies no regressions.
