aco: optimize v_add(v_bcnt(a, 0), b) to v_bcnt(a, b)
...
The first operand of v_bcnt should always be a VGPR because if it's
a SGPR, isel selects s_bcnt1 but I added a sanity check to prevent
any problems.

aco: optimize v_mad_u32_u16 with acc=0 to v_mul_u32_u24
...
v_mad_u32_u16 will be selected by isel to keep the range analysis
information around and to combine more v_add_u32+v_mad_u32_u16
together. When it's not possible to optimize that pattern, fallback
to v_mul_u32_u24 which is VOP2 instead of VOP3.
No fossils-db changes.

aco: fix combining add/sub to b2i if a new dest needs to be allocated
...
The uses vector needs to be expanded to avoid out of bounds access
and to make sure the number of uses is initialized to 0.
This fixes combining more v_and(a, v_subbrev_co_u32).
