As noticed in D87637, when LLDB crashes, we only print stack traces if
LLDB is directly executed, not when used via Python bindings. Enabling
this by default may be undesirable (libraries shouldn't be messing with
signal handlers), so make this an explicit opt-in.
I "commandeered" this patch from Jordan Rupprecht who put this up for
review originally.

The code to check if the regular LTO summary should be emitted and to
add the corresponding module flags was duplicated in the
'EmitAssemblyHelper::EmitAssemblyWithLegacyPassManager' and
'EmitAssemblyHelper::RunOptimizationPipeline' methods.
In order to eliminate these code duplications, the
'EmitAssemblyHelper::shouldEmitRegularLTOSummary' method has been
extracted. The method returns a bool value, the value is 'true' if the
module summary should be emitted. The patch keeps the setting of the
module flags inline.

This case is handled in neither the folding or canonicalization
patterns. The folding pattern cannot generate new broadcast ops,
so it should be handled by the canonicalization pattern.

We should only process APIs declared in the command line inputs to avoid
drowning the ExtractAPI output with symbols the user doesn't care about.
This is achieved by keeping track of the provided input files and
checking that the associated Decl or Macro is declared in one of those files.

Sometimes we can infer an align from an allocalign but the function
already promised it'd be more-aligned than the allocalign and there's an
existing align that we shouldn't reduce. Make sure we handle that
correctly.

This got changed to use hasAttrSomewhere() during review, and I didn't
notice until today when I was writing some tests for another part of
this system that using hasAttrSomewhere only checked the callsite for
allocalign, rather than both the callsite and the definition. This fixes
that by introducing a helper method.

This change is essentially a mechanical change which moves the thread
creation and join implementations from src/threads/linux to
src/__support/threads/linux/thread.h. The idea being that, in future, a
pthread implementation can reuse the common thread implementations in

Introduce _LIBCPP_ASSERTIONS_DISABLE_ASSUME which makes _LIBCPP_ASSERT
not call __builtin_assume when _LIBCPP_ENABLE_ASSERTIONS == 0.
Calling __builtin_assume was introduced in D122397.
__builtin_assume is generally supposed to improve optimizations, but can
cause regressions when LLVM has trouble handling the calls to
`llvm.assume()` (see comments in D122397).

- isValid: FileManager only ever returns valid FileEntries (see next point)
- construction from outside FileManager (both FileEntry and DirectoryEntry).
It's not possible to create a useful FileEntry this way, there are no setters.
This was only used in FileEntryTest, added a friend to enable this.
A real constructor is cleaner but requires larger changes to FileManager.

This is a lshr equivalent to D122340 - if we don't demand any of the additional sign bits introduced by the ashr, the lshr can be treated as an ashr and we can remove the shift entirely if we only demand already known sign bits.
