DebugInfo: Ensure that all debug location scope chains from instructions within a function, lead to the function itself.
Originally committed in r211723, reverted in r211724 due to failure

Original commit message:
PR20038: DebugInfo: Inlined call sites where the caller has debug info
but the call itself has no debug location.
This situation does bad things when inlined, so I've fixed Clang not to
produce inlinable call sites without locations when the caller has debug
info (in the one case where I could find that this occurred). This
updates the PR20038 test case to be what clang now produces, and readds
the assertion that had to be removed due to this bug.
I've also beefed up the debug info verifier to help diagnose these
issues in the future, and I hope to add checks to the inliner to just
assert-fail if it encounters this situation. If, in the future, we
decide we have to cope with this situation, the right thing to do is
probably to just remove all the DebugLocs from the inlined instructions.

Suppress inlining when the block address is taken
Inlining functions with block addresses can cause many problem and requires a
rich infrastructure to support including escape analysis. At this point the
safest approach to address these problems is by blocking inlining from
happening.
Background:
There have been reports on Ruby segmentation faults triggered by inlining
functions with block addresses like
//Ruby code snippet
vm_exec_core() {
finish_insn_seq_0 = &&INSN_LABEL_finish;
INSN_LABEL_finish:
;
}
This kind of scenario can also happen when LLVM picks a subset of blocks for
inlining, which is the case with the actual code in the Ruby environment.
LLVM suppresses inlining for such functions when there is an indirect branch.
The attached patch does so even when there is no indirect branch. Note that
user code like above would not make much sense: using the global for jumping
across function boundaries would be illegal.
Why was there a segfault:
In the snipped above the block with the label is recognized as dead So it is
eliminated. Instead of a block address the cloner stores a constant (sic!) into
the global resulting in the segfault (when the global is used in a goto).
Why had it worked in the past then:
By luck. In older versions vm_exec_core was also inlined but the label address
used was the block label address in vm_exec_core. So the global jump ended up
in the original function rather than in the caller which accidentally happened
to work.
Test case ./tools/clang/test/CodeGen/indirect-goto.c will fail as a result
of this commit.

Calls to this new builtin will map to instruction RDPMC.

Factored out Linux proc file reading into separate class.
Both NativeProcessLinux (in llgs branch) and Linux Host.cpp had similar code to handle /proc
file reading. I factored that out into a new Linux-specific ProcFileReader class and added a method
that the llgs branch will use for line-by-line parsing.
This change also adds numerous Linux-specific files to Xcode that were missing from the Xcode
project files.

CodeGenAction::ExecuteAction(): check for invalid LLVM source locations
Add sign checks to deal with the fact that IR parser line/column pairs are
signed integers and sometimes invalid.
The crash path is potentially triggered by corrupt '.bc' files in practice,
though I don't have a binary input test case that can be checked-in right now.
(Unfortunately the backend itself crashes on various ill-formed '.bc' inputs so
this bandage isn't as helpful as it appears yet.)

added.

Basic: correct the va_list type on Windows on ARM
Windows on ARM defines va_list as a typedef for char *. Although the semantics
of argument passing for variadic functions matches AAPCS VFP, the wrapped
struct __va_list type is unused. This makes the intrinsic definition for
va_list match that of Visual Studio.

Summary:
The first version failed the SubstNonTypeTempateParmExpr-related test
on some buildbots. This one uses the new substNonTypeTempateParmExpr matcher to
filter out implicit C-style casts.
This patch depends on D4327.

MC: rename EmitWin64EH routines
Rename the routines to reflect the reality that they are more related to call
frame information than to Win64 EH. Although EH is implemented in an intertwined
manner by augmenting with an exception handler and an associated parameter, the
majority of these routines emit information required to unwind the frames. This
also helps identify that these routines are generic for most windows platforms
(they apply equally to nearly all architectures except x86) although the
encoding of the information is architecture dependent.
Unwinding data is emitted via EmitWinCFI* and exception handling information via
EmitWinEH*.
