Following up on the removal of BufferPSV in commit 43b86bf992 ("AMDGPU:
Remove BufferPseudoSourceValue")
It is unclear what exactly the right address space for images should be.
They seem morally closest to buffers, so that's what I went with. In
practical terms, address space 7 is better than address space 0 because
it can't alias with LDS.

The use of a PSV for buffer intrinsics is misleading because it may be
misinterpreted as all buffer intrinsics accessing the same address in
memory, which is clearly not true.
Instead, build MachineMemOperands without a pointer value but with an
address space, so that address space-based alias analysis can still
work.
There is a lot of test churn because previously address space 4
(constant address space) was used as an address space for buffer
intrinsics. This doesn't make much sense and seems to have been an
accident -- see the change in
AMDGPUTargetMachine::getAddressSpaceForPseudoSourceKind.

This will currently accept the old number of bytes syntax, and convert
it to a scalar. This should be removed in the near future (I think I
converted all of the tests already, but likely missed a few).
Not sure what the exact syntax and policy should be. We can continue
printing the number of bytes for non-generic instructions to avoid
test churn and only allow non-scalar types for generic instructions.
This will currently print the LLT in parentheses, but accept parsing
the existing integers and implicitly converting to scalar. The
parentheses are a bit ugly, but the parser logic seems unable to deal
without either parentheses or some keyword to indicate the start of a
type.
Replace individual operands GLC, SLC, and DLC with a single cache_policy
bitmask operand. This will reduce the number of operands in MIR and I hope
the amount of code. These operands are mostly 0 anyway.
Additional advantage that parser will accept these flags in any order unlike
now.

Allow parsing generated mir with custom pseudo source value tokens.
Also rename pseudo source values to have more meaningful names.
