[AMDGPU] Enable 48-bit mul in AMDGPUCodeGenPrepare.
We were bailing out of creating 24-bit muls for results wider than 32
bits in AMDGPUCodeGenPrepare. With the 24-bit mulhi intrinsic, this
change teaches AMDGPUCodeGenPrepare to generate the 48-bit mul
correctly.

[AMDGPU] Fix 24-bit mul intrinsic generation for > 32-bit result.
The 24-bit mul intrinsics yields the low-order 32 bits. We should only
do the transformation if the operands are known to be not wider than 24
bits and the result is known to be not wider than 32 bits.

AMDGPU: Add 24-bit mul intrinsics
Insert these during codegenprepare.
This works around a DAG issue where generic combines eliminate the and
asserting the high bits are zero, which then exposes an unknown read
source to the mul combine. It doesn't worth the hassle of trying to
insert an AssertZext or something to try to deal with it.
