MemRef types now can carry an attribute to represent the memory
space. Still, upper layers in the compilation stack mostly use
nuemric values. They don't mean much (other than differentiating
separate memory domains) in MLIR's multi-level settings. Those
numeric memory space inside MemRef types need to be translated
into concrete SPIR-V storage classes during lowering to pin down
to concrete memory types.

Thus far we have been hardcoding an arbitrary mapping from memory
space to storage class for converting MemRef types. This works fine
for only targeting Vulkan; it falls apart if we want to target other
SPIR-V consumers like OpenCL, as different consumers might want
different storage classes for the buffer/variable of the same
lifetime. For example, StorageClass in Vulkan vs. CrossWorkgroup

AMDGPU/clang: Remove dead code

The order has to be a constant and should be enforced by the builtin
definition. The fallthrough behavior would have been broken anyway.

There's still an existing issue/assert if you try to use garbage for the
ordering. The IRGen should be broken, but we also hit another assert
before that.

[RISCV] Relax another one use restriction in performSRACombine.

When folding (sra (add (shl X, 32), C1), 32 - C) -> (shl (sext_inreg (add X, C1), i32), C)
it's possible that the add is used by multiple sras. We should
allow the combine if all the SRAs will eventually be updated.

After transforming all of the sras, the shls will share a single
(sext_inreg (add X, C1), i32).

This pattern occurs if an sra with 32 is used as index in multiple
GEPs with different scales. The shl from the GEPs will be combined
with the sra before we get a chance to match the sra pattern.
