Rebase: [Facebook] [MC] Introduce NeverAlign fragment type
Summary:
Introduce NeverAlign fragment type.
The intended usage of this fragment is to insert it before a pair of
macro-op fusion eligible instructions. NeverAlign fragment ensures that
the next fragment (first instruction in the pair) does not end at a
given alignment boundary by emitting a minimal size nop if necessary.
In effect, it ensures that a pair of macro-fusible instructions is not
split by a given alignment boundary, which is a precondition for
macro-op fusion in modern Intel Cores (64B = cache line size, see Intel
Architecture Optimization Reference Manual, 2.3.2.1 Legacy Decode
Pipeline: Macro-Fusion).
This patch introduces functionality used by BOLT when emitting code with
MacroFusion alignment already in place.
The use case is different from BoundaryAlign and instruction bundling:
- BoundaryAlign can be extended to perform the desired alignment for the
first instruction in the macro-op fusion pair (D101817). However, this
approach has higher overhead due to reliance on relaxation as
BoundaryAlign requires in the general case - see
https://reviews.llvm.org/D97982#2710638.
- Instruction bundling: the intent of NeverAlign fragment is to prevent
the first instruction in a pair ending at a given alignment boundary, by
inserting at most one minimum size nop. It's OK if either instruction
crosses the cache line. Padding both instructions using bundles to not
cross the alignment boundary would result in excessive padding. There's
no straightforward way to request instruction bundling to avoid a given
end alignment for the first instruction in the bundle.

Perform a major refactoring of vCont-threads tests in order to attempt
to improve their stability and performance.
Split test_vCont_run_subset_of_threads() into smaller test cases,
and split the whole suite into two files: one for signal-related tests,
the running-subset-of tests.
Eliminate output_match checks entirely, as they are fragile to
fragmentation of output. Instead, for the initial thread list capture
raise an explicit SIGINT from inside the test program, and for
the remaining output let the test program run until exit, and check all
the captured output afterwards.
For resume tests, capture the LLDB's thread view before and after
starting new threads in order to determine the IDs corresponding
to subthreads rather than relying on program output for that.
Add a mutex for output to guarantee serialization. A barrier is used
to guarantee that all threads start before SIGINT, and an atomic bool
is used to delay prints from happening until after SIGINT.
Call std::this_thread::yield() to reduce the risk of one of the threads
not being run.
This fixes the test hangs on FreeBSD. Hopefully, it will also fix all
the flakiness on buildbots.

[LoopVectorize] Add option to use active lane mask for loop control flow
Currently, for vectorised loops that use the get.active.lane.mask
intrinsic we only use the mask for predicated vector operations,
such as masked loads and stores, etc. The loop itself is still
controlled by comparing the canonical induction variable with the
trip count. However, for some targets this is inefficient when it's
cheap to use the mask itself to control the loop.
This patch adds support for using the active lane mask for control
flow by:
1. Generating the active lane mask for the next iteration of the
vector loop, rather than the current one. If there are still any
remaining iterations then at least the first bit of the mask will
be set.
2. Extract the first bit of this mask and use this bit for the
conditional branch.
I did this by creating a new VPActiveLaneMaskPHIRecipe that sets
up the initial PHI values in the vector loop pre-header. I've also
made use of the new BranchOnCond VPInstruction for the final

[DebugInfo][InstrRef] Fix error in copy handling in InstrRefLDV
Currently, an error exists when InstrRefBasedLDV observes transfers of
variables across copies, which causes it to lose track of variables
under certain circumstances, resulting in shorter lifetimes for those
variables as LDV gives up searching for live locations for them. This
patch fixes this issue by storing the currently tracked values in

clobbering or assigning them the wrong value.

[C++20][Modules] Implement include translation.
This addresses [cpp.include]/7
(when encountering #include header-name)
If the header identified by the header-name denotes an importable header, it
is implementation-defined whether the #include preprocessing directive is
instead replaced by an import directive.
In this implementation, include translation is performed _only_ for headers
in the Global Module fragment, so:
```
module;
#include "will-be-translated.h" // IFF the header unit is available.
export module M;
#include "will-not-be-translated.h" // even if the header unit is available
```
The reasoning is that, in general, includes in the module purview would not
be validly translatable (they would have to immediately follow the module
decl and without any other intervening decls). Otherwise that would violate
the rules on contiguous import directives.
This would be quite complex to track in the preprocessor, and for relatively
little gain (the user can 'import "will-not-be-translated.h";' instead.)

This patch adds the ability to use `-mllvm` options in the linker

This is done by passing in the LLVM argument to the clang-linker-wrapper
tool. Inside the linker-wrapper tool we invoke the `CommandLine` parser
solely for forwarding command line options to the `clang-linker-wrapper`
to the LLVM tools that also use the `CommandLine` parser. The actual
arguments to the linker wrapper are parsed using the `Opt` library
instead.
For example, in the following command the `CommandLine` parser will attempt to
parse `abc`, while the `opt` parser takes `-mllvm <arg>` and ignores it so it is
not passed to the linker arguments.
```
clang-linker-wrapper -mllvm -abc -- <linker-args>

LLVM tool invocations. If there is a better way to pass these arguments
