ce5c6091e0 Don't reduce the stack protector level given -fstack-protector.
Before -fstack-protector would always force a level of 1, even if the default
was 2.

Call it "libclang_rt.builtins-<arch>.a" to be consistent
with sanitizers/profile libraries naming. Modify Makefile

b5b622a03c Drop non-cfi assembly support from clang.
After this patch clang will ignore -fdwarf2-cfi-asm and -ffno-dwarf2-cfi-asm and
always print assembly that uses cfi directives.

In llvm, MC itself supports cfi since the end of 2010 (support started
in r119972, is reported in the 2.9 release notes).

In binutils the support has been around for much longer. It looks like
support started to be added in May 2003. It is available in 2.15
(31-Aug-2011, 2.14 is from 12-Jun-2003).

829b170048 Add support for optimization reports.
Summary:
This patch adds a new flag -Rpass=. The flag indicates the name
of the optimization pass that should emit remarks stating when it
made a transformation to the code.

This implements the design I proposed in:

https://docs.google.com/document/d/1FYUatSjZZO-zmFBxjOiuOzAy9mhHA8hqdvklZv68WuQ/edit?usp=sharing

Other changes:
- Add DiagnosticIDs::isRemark(). Use it in printDiagnosticOptions to
  print "-R" instead of "-W" in the diagnostic message.

- In BackendConsumer::OptimizationRemarkHandler, get a SourceLocation
  object out of the file name, line and column number. Use that location
  in the call to Diags.Report().

- When -Rpass is used without debug info a note is emitted alerting
  the user that they need to use -gline-tables-only -gcolumn-info to
  get this information.

d971cd1b18 InstrProf: Emit runtime hook directly in IRGen
-u behaviour is apparently not portable between linkers (see cfe-commits
discussions for r204379 and r205012).  I've moved the logic to IRGen,
where it should have been in the first place.

I don't have a Linux system to test this on, so it's possible this logic
*still* doesn't pull in the instrumented profiling runtime on Linux.

I'm in the process of getting tests going on the compiler-rt side
(llvm-commits "[PATCH] InstrProf: Add initial compiler-rt test").  Once
we have tests for the full flow there, the runtime logic should get a
whole lot less brittle.
