With the transition to opaque pointers, type information has been
transferred to function parameter attributes. This patch adds correct
parsing for some of those arguments and fixes some tests, that
previously used UnitAttr for those.

This patch "modernizes" the LLVM `insertvalue` and `extractvalue`
operations to use DenseI64ArrayAttr, since they only require an array of
indices and previously there was confusion about whether to use i32 or
i64 arrays, and to use assembly format.

This patch adds three new LLVM intrinsic operations: llvm.intr.vastart/copy/end.
And its translation from LLVM IR.
This effectively removes a restriction, imposed by 0126dcf1f0a1, where
non-external functions in LLVM dialect cannot be variadic. At that time
it was not clear how LLVM intrinsics are going to be modeled, which
indirectly affects va_start/copy/end, the core intrinsics used in
variadic functions. But since we have LLVM intrinsics as normal
MLIR operations, it's not a problem anymore.

The 'emit_c_wrappers' option in the FuncToLLVM conversion requests C interface
wrappers to be emitted for every builtin function in the module. While this has
been useful to bootstrap the interface, it is problematic in the longer term as
it may unintentionally affect the functions that should retain their existing
interface, e.g., libm functions obtained by lowering math operations (see
D126964 for an example). Since D77314, we have a finer-grain control over
interface generation via an attribute that avoids the problem entirely. Remove
the 'emit_c_wrappers' option. Introduce the '-llvm-request-c-wrappers' pass
that can be run in any pipeline that needs blanket emission of functions to
annotate all builtin functions with the attribute before performing the usual
lowering that accounts for the attribute.

This patch adds support for Calling Convention attribute in LLVM
dialect, including enums, custom syntax and import from LLVM IR.
Additionally fix import of dso_local attribute.

Originally in the returnOp conversion, the result type was changing to bare
pointer if the type was a memref. This is incorrect as conversion to bare
pointer can only be done if the memref has static shape, strides and offset.

This removes any potential confusion with the `getType` accessors
which correspond to SSA results of an operation, and makes it
clear what the intent is (i.e. to represent the type of the function).

When using `--convert-func-to-llvm=emit-c-wrappers` the attribute arguments of the wrapper would not be created correctly in some cases.
This patch fixes that and introduces a set of tests for (hopefully) all corner cases.

The current StandardToLLVM conversion patterns only really handle
the Func dialect. The pass itself adds patterns for Arithmetic/CFToLLVM, but
those should be/will be split out in a followup. This commit focuses solely
on being an NFC rename.
Aside from the directory change, the pattern and pass creation API have been renamed:
* populateStdToLLVMFuncOpConversionPattern -> populateFuncToLLVMFuncOpConversionPattern
* populateStdToLLVMConversionPatterns -> populateFuncToLLVMConversionPatterns
* createLowerToLLVMPass -> createConvertFuncToLLVMPass
