[RISCV] Improve variable scoping in custom isel for ISD::AND.
Give the (and (srl/shl X, C2), C1) handling its owns private `C1` variable
it can modify using known zeros. This may be out of sync with
N1C->getZExtValue().
Add a separate const C1 for (and (sra X, C2), C1) and (and X, C).
This copy will always be in sync with N1C->getZExtValue().
Remove the IsC1Mask and IsC1ANDI variables and compute them at their
usage.
Use N1C->getSExtValue() when calling isInt. This shouldn't be a
functional change since we already checked that it was a mask. In
order for it to be a mask and a negative number, it would need to be -1
which should have been removed by DAG combine.
