Stanislav Mekhanoshin d445455643 [AMDGPU] Add pattern for v_alignbit_b32 with immediate 
If immediate in shift is less than 32 we can use alignbit too.

Stanislav Mekhanoshin eb40733bf0 Allow to truncate left shift with non-constant shift amount 
That is pretty common for clang to produce code like
(shl %x, (and %amt, 31)). In this situation we can still perform
trunc (shl) into shl (trunc) conversion given the known value
range of shift amount.
