Summary:
In rL299692 I improved strip-dead-debug-info's ability to drop CUs that are not
referenced from the current module. However, in doing so I neglected to realize
that some SPs could be referenced entirely from inlined functions. It appears
I was not the only one to make this mistake, because DebugInfoFinder, doesn't
find those SPs either. Fix this in DebugInfoFinder and then use that to make
sure not to drop those CUs in strip-dead-debug-info.

The files there can always be referred to using their full path, which
is what most of the code has been doing already, so this makes the
situation more consistent. Also fix the the code in the FreeBSD plugin
to use the new paths.

Use the same handling in the generic legalizer code as for the other

Enable it on ARM for float and double so we can test it.

A fix for the bug reported in PR30911.

The issue arises when multiple CALLSEQ_BEGIN nodes are unscheduled as
the last node to be unscheduled will gain access to the CallResource
register. But when a node is being picked, only CALLSEQ_END nodes are
checked against the CallResource and have their chains evaluated.
This then means that other CALLSEQ_BEGIN nodes can be scheduled
before the existing call sequence has been finalised. This patch adds
a check against the FrameSetup nodes in DelayForLiveRegs to prevent
this from happening.

Module::getOrInsertFunction is using C-style vararg instead of
variadic templates.

From a user prospective, it forces the use of an annoying nullptr
to mark the end of the vararg, and there's not type checking on the
arguments. The variadic template is an obvious solution to both
issues.

Previously in r297800, a work-around was created to use TSC emulation on x86_64 when RDTSCP was not available on the host. A similar change was needed in the file xray_fdr_logging.cc which this patch ports over to that file.

Eventually the code should be refactored as there will be 3 locations with the same code, but that can be done as a separate step. This patch is just to keep the test from failing on my machine due to an illegal instruction since RDTSCP is not available on my x86_64 linux VM.

[InstCombine] Refinement of r299915. Only consider a ConstantVector for Neg if all the elements are Undef or ConstantInt.

llvm-svn: 299917

Summary:
We can move this functionality into LLVM's tools instead, as it no
longer is strictly required for the compiler-rt testing infrastructure.
It also is blocking the successful bootstrapping of the clang compiler
due to a missing virtual destructor in one of the flag parsing library.

Since this binary isn't critical for the XRay runtime testing effort
anymore (yet), we remove it in the meantime with the hope of moving the
functionality in LLVM proper instead.

(h/t to Chandler for pointing this out)

The test in question was not at all testing what it was supposed to
test.  We do not //care// about placing `!make.implicit` in inner
constant branch (since it will be folded away anyway).  We care about
placing `!make.implicit` in the outer branch that switches between
either version of the loop.

Having said that, it is _correct_ to leave behind the `!make.implicit`
in the inner branch, but there is no need to do so.
