When bit-field data was stored in a Scalar in ValueObjectChild during UpdateValue()
it was extracting the bit-field value. Later on in lldb_private::DumpDataExtractor(…)
we were again attempting to extract the bit-field. Which would then not obtain the
correct value. This will remove the extra extraction in UpdateValue().
We hit this specific case when values are passed in registers, which we could only
reproduce in an optimized build.

Demoting unreferenced externals is unsafe if multiple interdependent test
objects are used, including objects loaded from archives.

MachO TLV relocations aren't supported yet. Error out rather than falling
through to llvm_unreachable.

Add support for -arch_only option for llvm-libtool-darwin. This diff
also adds support for accepting universal files as input and flattening
them to create the required static library. Supports input universal
files contaning both Mach-O object files or archives.

Differences from cctools' libtool:
- `-arch_only` can be specified multiple times
- archives containing universal files are considered invalid (libtool
allows such archives)

OpenACC combined construct can have an optional end directive. This patch handle this
case in the parsing/unparsing with a canonicalization step. Unlike OmpEndLoopDirective,
this doesn't need a special treatment in the pre-fir tree as there is no clause attached to

rG9bd97d03 caused a miscompile of this internal test case

Instead of clearing the launch flags, always pass the target's current
launch flags.

This exercises the corner case that was fixed in
https://reviews.llvm.org/rG8979a9cdf226066196f1710903d13492e6929563.

The bug can be reproduced when there is a @callee with a custom type argument and @caller has a producer of this argument passed to the @callee.

Example:
func @callee(!test.test_type) -> i32
func @caller() -> i32 {
  %arg = "test.type_producer"() : () -> !test.test_type
  %out = call @callee(%arg) : (!test.test_type) -> i32
  return %out : i32
}

Even though there is a type conversion for !test.test_type, the output IR (before the fix) contained a DialectCastOp:

module {
  llvm.func @callee(!llvm.ptr<i8>) -> !llvm.i32
  llvm.func @caller() -> !llvm.i32 {
    %0 = llvm.mlir.null : !llvm.ptr<i8>
    %1 = llvm.mlir.cast %0 : !llvm.ptr<i8> to !test.test_type
    %2 = llvm.call @callee(%1) : (!test.test_type) -> !llvm.i32
    llvm.return %2 : !llvm.i32
  }
}

instead of

module {
  llvm.func @callee(!llvm.ptr<i8>) -> !llvm.i32
  llvm.func @caller() -> !llvm.i32 {
    %0 = llvm.mlir.null : !llvm.ptr<i8>
    %1 = llvm.call @callee(%0) : (!llvm.ptr<i8>) -> !llvm.i32
    llvm.return %1 : !llvm.i32
  }
}

Summary:
This enables sharing the logic between standalone clangd and embedders
of it. The new approach should be same performance-wise, as it is only called
once per addDocument call.

This patch also introduces a blacklisting code path for disabling crashy or
high-noise tests, until we figure out a way to make them work with clangd-setup.

The biggest difference is the way we make use of preambles, hence those checks
can't see directives coming from the preamble section of the file. The second
thing is the fact that code might-not be compiling while clangd is trying to
build an AST, hence some checks might choke on those incomplete ASTs.

Summary:
Some clang-tidy checkers, e.g. llvm-include-order can emit diagnostics
at this callback (as mentioned in the comments).

Clangd was resetting diag consumer to IgnoreDiags before sending EOF, hence we
were unable to emit diagnostics for such checkers.

This patch changes the order of that reset and preprocosser event to make sure
we emit that diag.

Fixes https://github.com/clangd/clangd/issues/314.
