For variable pointers we really don't want to case the pointers to int
without a good reason, just add a wrapper for bcsel loading and result
storing.

On GFX9 whether the buffer size is interpreted as elements or bytes
depends on whether IDXEN is enabled in the instruction. If the index
is a constant zero, LLVM optimizes IDXEN to 0.
Now the size in elements is interpreted in bytes which of course
results in out of bounds accesses.
The correct fix is most likely to disable the LLVM optimization,
but we need something to work with LLVM <= 6.0.
radeonsi does the max between stride and element count on the CPU
but that results in the size intrinsics returning the wrong size
for the buffer. This would cause CTS errors for radv.
v2: Also include the store changes.
