Entry block count was not counted and is corrected. Also
introduce a new metric that is MaxInternalBlockCount which
show command shows (as before).

FIXME: Add more targets to use emutls into clang/test/Driver/emulated-tls.cpp.
FIXME: Add cygwin tests into llvm/test/CodeGen/X86. Working in progress.

Summary:
It's possible to BindArch without changing the toolchain at all. For
example, armv7 and armv7s have exactly the same toolchain triple.
Therefore the code in the Driver that checks that we're not creating a
job for the same Action twice needs to consider (Action, Toolchain,
BoundArch) tuples.

Summary:
Later in DWARF emission we check that DebugLocEntries have
non-overlapping pieces, so we should create any such entries
by merging here.
Fixes PR26163.

When generating a relocatable file, its only valid to set this flag if
all of the inputs also had the flag. Otherwise we may atomize incorrectly
when we link the relocatable file again.

Thread stack/TLS may be stored by libpthread for future reuse after
thread destruction, and the linked list it's stored in doesn't
even hold valid pointers to the objects, the latter are calculated
by obscure pointer arithmetic.
With this change applied, LSan test suite passes with
"use_ld_allocations" flag defaulted to "false". It still requires more
testing to check if the default can be switched.

The image info struct contains flags for what kind of GC/retain/release is required.
Give an error if we parse GC flags as these are unsupported.

The only functional change would be that we might emit multiple filename
segments on code like this:
void f() {
#include "p1/../t.h"
#include "p2/../t.h"
}
I believe these get separate DIFile metadata nodes, but will have the
same canonicalized absolute path. Previously by computing the path up
front and comparing it we would merge the line info segments.

WebAssembly's stack will never be executable by default, so it isn't
necessary to declare .note.GNU-stack sections to request a non-executable
stack.

The cases of this switch are all perfectly regular (except for the first case).
A macro is more readable here.
Thanks to Dave Blaikie for the suggestion.

It looks nicer and improves the compiletime of a typical
clang -O3 -emit-llvm run by ~0.6% for me.
