Matt Arsenault 9e5e868d95 AMDGPU/GlobalISel: Fix RegBankSelect for GEP.
This is basically a pointer typed add, so shouldn't be any different.
This was assuming everything was an SGPR, which is not true.

Also cleanup legality for GEP. I don't seem to be seeing the problem
the hack marking s64 as a legal pointer type the comment mentions.

Matt Arsenault b0a227049f AMDGPU/GlobalISel: Fix shift legalization for non-power-of-2
clampScalar doesn't do anything for non-power-of-2 in range.
There should probably be a combination rule to reduce the number
of matching rules.

that need the load from the queue ptr.

Matt Arsenault fbec8fe93b GlobalISel: Implement narrowScalar for shift main type
This is pretty much directly ported from SelectionDAG. Doesn't include
the shift by non-constant but known bits version, since there isn't a
globalisel version of computeKnownBits yet.

This shows a disadvantage of targets not specifically which type
should be used for the shift amount. If type 0 is legalized before
type 1, the operations on the shift amount type use the wider type
(which are also less likely to legalize). This can be avoided by
targets specifying legalization actions on type 1 earlier than for
type 0.

Matt Arsenault c83b82363c GlobalISel: Implement fewerElementsVector for shifts
Introduce a new function which handles instructions with multiple type
indices, but have the same number of vector elements.

Also legalize v2s16 shifts when applicable.

Matt Arsenault 18619afe1d GlobalISel: Fix narrowScalar for load/store with different mem size
This was ignoring the memory size, and producing multiple loads/stores
if the operand size was different from the memory size.

I assume this is the intent of not having an explicit G_ANYEXTLOAD
(although I think that would probably be better).
