The metric does not return the number of remaining (or inserted) copies

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.

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.

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.

By default it is off so no behavior change in backend.

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.

[X86] Add custom promotion of v2i8/v2i16 fp_to_sint to avoid over promotion to v2i64 which would force scalarization.

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.

It was causing a crash because we were trying to get the definition
of a target register. Fixed the issue by adding a check and added
