Mohammed Nurul Hoque 7afa44f5f5 [RISCV] Add more sign-extending ops to MIR sext.w pass. ...

This patch adds single-bit and bit-counting ops to list of sign-extending ops.

A single-bit write propagates sign-extendedness if it's not in the sign-bits.

Bit extraction and bit counting always outputs a small number, so sign-extended.
