IRMover: Avoid accidentally mapping types from the destination module (PR30799)
During Module linking, it's possible for SrcM->getIdentifiedStructTypes();
to return types that are actually defined in the destination module
(DstM). Depending on how the bitcode file was read,
getIdentifiedStructTypes() might do a walk over all values, including
metadata nodes, looking for types. In my case, a debug info metadata
node was shared between the two modules, and it referred to a type
defined in the destination module (see test case).

Add link-time detection of LLVM_ABI_BREAKING_CHECKS mismatch

LLVM will define a symbol, either EnableABIBreakingChecks or

[CUDA] Driver changes to support CUDA compilation on MacOS.
Summary:
Compiling CUDA device code requires us to know the host toolchain,
because CUDA device-side compiles pull in e.g. host headers.
When we only supported Linux compilation, this worked because
CudaToolChain, which is responsible for device-side CUDA compilation,
inherited from the Linux toolchain. But in order to support MacOS,
CudaToolChain needs to take a HostToolChain pointer.
Because a CUDA toolchain now requires a host TC, we no longer will
create a CUDA toolchain from Driver::getToolChain -- you have to go
through CreateOffloadingDeviceToolChains. I am *pretty* sure this is
correct, and that previously any attempt to create a CUDA toolchain
through getToolChain() would eventually have resulted in us throwing
"error: unsupported use of NVPTX for host compilation".
In any case hacking getToolChain to create a CUDA+host toolchain would
be wrong, because a Driver can be reused for multiple compilations,
potentially with different host TCs, and getToolChain will cache the
result, causing us to potentially use a stale host TC.
So that's the main change in this patch.
In addition, we have to pull CudaInstallationDetector out of Generic_GCC
and into a top-level class. It's now used by the Generic_GCC and MachO
toolchains.

Always compute sh_link for SHF_LINK_ORDER sections.
Since the output has a section table too, it is meaningful to compute
the sh_link. In a more practical note, the binutils' strip crashes if
sh_link is not set for SHT_ARM_EXIDX.

Minor changes in x86 intrinsics headers; NFC
I made several changes for consistency with the rest of x86 instrinsics header files. Some of these changes help to render doxygen comments better.
1. avxintrin.h – Moved the opening bracket on a separate line for several
intrinsics (for consistency with the rest of the intrinsics).
2. emmintrin.h - Moved the doxygen comment next to the body of the function;
- Added braces after extern "C" even though there is only
one declaration each time
3. xmmintrin.h - Moved the doxygen comment next to the body of the function;
- Added intrinsic prototypes for a couple of macro definitions
into the doxygen comment;
- Added braces after extern "C" even though there is only one
declaration each time
4. ammintrin.h – Removed extra line between the doxygen comment and the body
of the functions (for consistency with the rest of the files).

[Preprocessor] Support for '-dI' flag
Re-introduce r285411.
Implement the -dI as supported by GCC: Output ‘#include’ directives in addition
to the result of preprocessing.
This change aims to add this option, pass it through to the preprocessor via
the options class, and when inclusions occur we output some information (+ test
cases).

Fix step-over when SymbolContext.function is missing and symbol is present.
Summary:
Fix step-over when SymbolContext.function is missing and symbol is present.
With targets from our build configuration,
ThreadPlanStepOverRange::IsEquivalentContext fails to fire for relevant frames,
leading to ShouldStop() returning true prematurely.
The frame's SymbolContext, and m_addr_context have:
- comp_unit set and matching
- function = nullptr
- symbol set and matching (but this is never checked)
My naive guess is that the context should be equivalent in this case :-)

Allow use define symbols to override linker defined ones.
I hit an internal linker script that was defining _DYNAMIC instead of
letting the linker do it. It turns out that both bfd and gold allow
that.
This is pretty easy to implement, just make the linker defined symbol
weak. This should have no impact in the case where there is no user
defined symbol: The visibility is hidden, which causes the output to
still be local.

Allow SIZEOF() command on nonexistent section.
Linker script doesn't create a section if it has no content. So the following
script doesn't create .norelocs section if it doesn't have any .rel* sections.
.norelocs : { *(.rel*) }
Later, if you assert that the size of .norelocs is 0, LLD printed out
an error message, because it didn't allow calling SIZEOF() on nonexistent
sections.
This patch allows SIZEOF() on nonexistent sections, so that you can do
something like this.
ASSERT(SIZEOF(.norelocs), "shouldn't contain .rel sections!")
