Recent commits added a possibility for indices in LLVM dialect GEP operations

In LLVM IR, the GEP indices that correspond to structures are required to be

[lldb] Compute fully qualified command names in FindCommandsForApropos
Fixes incomplete command names in `apropos` results.
The full command names given by `apropos` have come from command name string
literals given to `CommandObject` constructors. For most commands, this has
been accurate, but some commands have incorrect strings. This results in
`apropos` output that doesn't tell the user the full command name they might
want learn more about. These strings can be fixed.
There's a seperate issue that can't be fixed as easily: plugin commands. With
the way they're implemented, plugin commands have to exclude the root command
from their command name string. To illustrate, the `language objc` subcommand
has to set its command name string to "objc", which results in apropos printing
results as `objc ...` instead of `language objc ...`.
To fix both of these issues, this commit changes `FindCommandsForApropos` to
derive the fully qualified command name using the keys of subcommand maps.

Disable clang-tidy warnings from system macros
Currently, it's inconsistent that warnings are disabled if they
come from system headers, unless they come from macros.
Typically a user cannot act upon these warnings coming from
system macros, so clang-tidy should ignore them unless the
user specifically requests warnings from system headers
via the corresponding configuration.
This change broke the ProTypeVarargCheck check, because it
was checking for the usage of va_arg indirectly, expanding it
(it's a system macro) to detect the usage of __builtin_va_arg.
The check has been fixed by checking directly what the rule
is about: "do not use va_arg", by adding a PP callback that
checks if any macro with name "va_arg" is expanded. The old
AST matcher is still kept for compatibility with Windows.
Add unit test that ensures warnings from macros are disabled

[RISCV] Use simm5_plus1_nonzero in isel patterns for vmsgeu.vi/vmsltu.vi intrinsics.
The 0 immediate can't be selected to vmsgtu.vi/vmsleu.vi by decrementing
the immediate. To prevent his we had special patterns that provided
alternate lowering for the 0 cases. This relied on tablegen prioritizing
the 0 pattern over the sim5_plus1 range.
This patch introduces simm5_plus1_nonzero that excludes 0. It also
excludes the special case for vmsltu.vi since we can just use
vmsltu.vx and let the 0 be selected to X0.

[RISCV] Add an MIR pass to replace redundant sext.w instructions with copies.
Function calls and compare instructions tend to cause sext.w
instructions to be inserted. If we make good use of W instructions,
these operations can often end up being redundant. We don't always
detect these during SelectionDAG due to things like phis. There also
some cases caused by failure to turn extload into sextload in
SelectionDAG. extload selects to LW allowing later sext.ws to become
redundant.
This patch adds a pass that examines the input of sext.w instructions trying
to determine if it is already sign extended. Either by finding a
W instruction, other instructions that produce a sign extended result,
or looking through instructions that propagate sign bits. It uses
a worklist and visited set to search as far back as necessary.

[RISCV] Don't advertise i32->i64 zextload as free for RV64.
The zextload hook is only used to determine whether to insert a
zero_extend or any_extend for narrow types leaving a basic block.
Returning true from this hook tends to cause any load whose output
leaves the basic block to become an LWU instead of an LW.
Since we tend to prefer sexts for i32 compares on RV64, this can
cause extra sext.w instructions to be created in other basic blocks.
If we use LW instead of LWU this gives the MIR pass from D116397
a better chance of removing them.
Another option might be to teach getPreferredExtendForValue in
FunctionLoweringInfo.cpp about our preference for sign_extend of
i32 compares. That would cause SIGN_EXTEND to be chosen for any
value used by a compare instead of using the isZExtFree heuristic.
That will require code to convert from the llvm::Type* to EVT/MVT
as well as querying the type legalization actions to get the
promoted type in order to call TargetLowering::isSExtCheaperThanZExt.
That seemed like many extra steps when no other target wants it.
Though it would avoid us needing to lean on the MIR pass in some cases.

[mlir][linalg][bufferize][NFC] Use RewritePatterns instead of custom traversal
This change simplifies BufferizableOpInterface and other functions. Overall, the API will get smaller: Functions related to custom IR traversal are deleted entirely. This will makes it easier to write BufferizableOpInterface implementations.
This is also in preparation of unifying Comprehensive Bufferize and core bufferization. While Comprehensive Bufferize could theoretically maintain its own IR traversal, there is no reason to do so, because all bufferize implementations in BufferizableOpInterface have to support partial bufferization anyway. And we can share a larger part of the code base between the two bufferizations.
