[OpenCL] Respect calling convention for builtin

`__translate_sampler_initializer` has a calling convention of
`spir_func`, but clang generated calls to it using the default CC.

Instruction Combining was lowering these mismatching calling conventions
to `store i1* undef` which itself was subsequently lowered to a trap
instruction by simplifyCFG resulting in runtime `SIGILL`

There are arguably two bugs here: but whether there's any wisdom in
converting an obviously invalid call into a runtime crash over aborting
with a sensible error message will require further discussion. So for
now it's enough to set the right calling convention on the runtime

[CodeGen] Fix issues with scalable-vector INSERT/EXTRACT_SUBVECTORs

This patch addresses a few issues when dealing with scalable-vector
INSERT_SUBVECTOR and EXTRACT_SUBVECTOR nodes.

When legalizing in DAGTypeLegalizer::SplitVecRes_INSERT_SUBVECTOR, we
store the low and high halves to the stack separately. The offset for
the high half was calculated incorrectly.

Additionally, we can optimize this process when we can detect that the
subvector is contained entirely within the low/high split vector type.
While this optimization is valid on scalable vectors, when performing
the 'high' optimization, the subvector must also be a scalable vector.
Note that the 'low' optimization is still conservative: it may be
possible to insert v2i32 into the low half of a split nxv1i32/nxv1i32,
but we can't guarantee it. It is always possible to insert v2i32 into
nxv2i32 or v2i32 into nxv4i32+2 as we know vscale is at least 1.

Lastly, in SelectionDAG::isSplatValue, we early-exit on the extracted subvector value
type being a scalable vector, forgetting that we can also extract a
fixed-length vector from a scalable one.

Prior to this pass, accesses from a function are compiled to trap. With this

This is of interest to the openmp project because the deviceRTL runtime library

The patch in question broke the build with shared libraries due to
missing dependencies, one of which would have been circular between
MLIRStandard and MLIRMemRef if added. Fix this by moving more code
around and swapping the dependency direction. MLIRMemRef now depends on
MLIRStandard, but MLIRStandard does _not_ depend on MLIRMemRef.
Arguably, this is the right direction anyway since numerous libraries
depend on MLIRStandard and don't necessarily need to depend on
MLIRMemref.

Other otable changes include:
- some EDSC code is moved inline to MemRef/EDSC/Intrinsics.h because it
  creates MemRef dialect operations;
- a utility function related to shape moved to BuiltinTypes.h/cpp

  (standard dialect is erroneously believed to contain MemRefType);
- a Python test for the standard dialect is disabled completely because

  exposed to Python bindings, and the change for that is non-trivial.

[RISCV] Support fixed-length vectors in the calling convention

This patch adds fixed-length vector support to the calling convention
when RVV is used to lower fixed-length vectors. The scheme follows the
regular vector calling convention for the argument/return registers, but
uses scalable vector container types as the LocVTs, and converts to/from
the fixed-length vector value types as required.

Fixed-length vector types may be split when the combination of minimum
VLEN and the maximum allowable LMUL is not large enough to fully contain
the vector. In this case the behaviour differs between fixed-length
vectors passed as parameters and as return values:
1. For return values, vectors must be passed entirely via registers or
via the stack.
2. For parameters, unlike scalar values, split vectors continue to be
passed by value, and are split across multiple registers until there are
no remaining registers. Thus vector parameters may be found partly in
registers and partly on the stack.

As with scalable vectors, the first fixed-length mask vector is passed
via v0. Split mask fixed-length vectors are passed first via v0 and then
via the next available vector register: v8,v9,etc.

The handling of vector return values uses all available argument
registers v8-v23 which does not adhere to the calling convention we're
supposedly implementing, but since this issue affects both fixed-length
and scalable-vector values, it was left as-is.

    folding and simplification, reducing iterations and re-evaluation of ops in
    simple cases.
 2) Explicitly enter existing constants into the OperationFolder table before
    canonicalizing.  Previously we would "constant fold" them and rematerialize
    them, wastefully recreating a bunch fo constants, which lead to pointless
    memory traffic.

Both changes together provide a 33% speedup for canonicalize on some mid-size
CIRCT examples.

One artifact of this change is that the constants generated in normal pattern
application get inserted at the top of the function as the patterns are applied.
Because of this, we get "inverted" constants more often, which is an aethetic
change to the IR but does permute some testcases.

[RISCV] Give an explicit error if 'generic' CPU is passed instead of 'generic-rv32' or 'generic-rv64'. Validate 64Bit feature against the triple.

I encountered a project that uses llvm that passes "generic" by
default. While I could fix that project, I wouldn't be surprised
if other projects did something similar. So it seems like
a good idea to provide a better error here.

I've also added validation of the 64Bit feature against the
triple so that we can catch a mismatched CPU before failing in
a mysterious way. We can make it pretty far in isel because we
calculate XLenVT from the triple and use that to set up the legal
integer type.
