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.

Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.
Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).

Summary:
This includes a hazard recognizer implementation to replace some of
the hazard handling we had during frame index elimination.

This breaks the tests that were meant for testing
64-bit inline immediates, so move those to shl where
they won't be broken up.
This should be repeated for the other related bit ops.
