As shown, this is used to eliminate redundant code in InstCombine,
and there are more cases where we should be using this pattern, but
we're currently unintentionally dropping flags.

Summary:
LLVM puts output binaries in
`${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/bin`. This chunk of
code left out the `${CMAKE_CFG_INTDIR}`. Ultimately, the code signing target
does not need a working directory anyways, so it's safe to just remove it.

Sink Windows version detection code from WindowsSupport.h to Path.inc.
These functions don't need to be inlined. I randomly picked Process.inc
for the Windows version helpers, since that's the most related file.
Sink MakeErrMsg to Program.inc since it's the main client.
Move those functions into the llvm namespace, and delete the scoped
handle copy and assignment operators.

Some weak external symbols were added to the profile runtime in D49953,
and on Darwin, these need to be exported for tapi verification purposes.
I've tightened the test so that future breakages can be caught earlier.

This feature makes it easy to tune FileCheck diagnostic output when
running the test suite via ninja, a bot, or an IDE. For example:
```
$ FILECHECK_OPTS='-color -v -dump-input-on-failure' \
LIT_FILTER='OpenMP/for_codegen.cpp' ninja check-clang \
| less -R
```

Instead of iterating over the leaves to find repeated substrings, and walking
collecting leaf children when we don't necessarily need them, let's just
calculate what we need and iterate over that.
By doing this, we don't have to save every leaf. It's easier to read the code
too and understand what's going on.
The goal here, at the end of the day, is to set up to allow us to do something
like
for (RepeatedSubstring &RS : ST) {
... do stuff with RS ...
}
Which would let us perform the cost model stuff and the repeated substring
query at the same time.

Add this option for debugging and providing workaround.

Summary:
Some CPUID leafs depend on the value of ECX as well as EAX, but we left

This speeds up process startup and teardown and also reduces lock contention when running multiple ASanified/TSanified processes simultaneously. Should greatly improve lit testing time.

Summary:
The NotEligibleToImport flag on the GlobalValueSummary was set if it
isn't legal to import (e.g. because it references unpromotable locals)
and when it can't be inlined (in which case importing is pointless).
I split out the inlinable piece into a separate flag on the
FunctionSummary (doesn't make sense for aliases or global variables),
because in the future we may want to import for reasons other than
inlining.

The lowering for a call to eh_typeid_for changes when it's moved from
one function to another.
There are several proposals for fixing this issue in llvm.org/PR39545.
Until some solution is in place, do not allow CodeExtractor to extract
calls to eh_typeid_for, as that results in serious miscompilations.
llvm-svn: 346256
When CodeExtractor moves instructions to a new function, debug
intrinsics referring to those instructions within the parent function
become invalid.
This results in the same verifier failure which motivated r344545, about
function-local metadata being used in the wrong function.

Change the type in a couple of lists and sets that only store physical
registers from unsigned to MCPhysRegs. The later is only 16bits and
saves us a bit of memory.

SmallVector was changed to store a begin and a size rather than a
begin and an end a while back. Update the formatter to look at the
correct members.

It was causing a crash because we were trying to get the definition
