When parsing C++ type construction expressions with list initialization,
forward the locations of the braces to Sema.
Without these locations, the code coverage pass crashes on the given test
case, because the pass relies on getLocEnd() returning a valid location.
Here is what this patch does in more detail:
- Forwards init-list brace locations to Sema (ParseExprCXX),
- Builds an InitializationKind with these locations (SemaExprCXX), and
- Uses these locations for constructor initialization (SemaInit).
The remaining changes fall out of introducing a new overload for
creating direct-list InitializationKinds.
Testing: check-clang, and a stage2 coverage-enabled build of clang with
asserts enabled.

This patch changes cc1 option -fprofile-instr-generate to an enum option
-fprofile-instrument={clang|none}. It also changes cc1 options
-fprofile-instr-generate= to -fprofile-instrument-path=.
The driver level option -fprofile-instr-generate and -fprofile-instr-generate=
remain intact. This change will pave the way to integrate new PGO
instrumentation in IR level.

We include unused functions and methods in -fcoverage-mapping so that
we can differentiate between uninstrumented and unused. This can cause
problems for uninstantiated templates though, since they may involve
an incomplete type that can't be mangled. This shows up in things like
libc++'s <unordered_map> and makes coverage unusable.
Avoid the issue by skipping uninstantiated methods of a templated
class.

Change the lit RUN commands for 3 tests to use the following pattern
"FileCheck -input-file ..." instead of "cat ... | FileCheck ..." as
suggested by Justin Bogner.

This patch adds the tests for the coverage mapping generation.
Most of the tests check the mapping regions produced by
the generator, and one checks the llvm IR.

I reverted one of the added tests from r215261 in r215274, since it
was failing on quite a few bots. It looks like this wasn't sufficient,
as we're still getting failures on windows, like the following:
http://bb.pgr.jp/builders/ninja-x64-msvc-RA-centos6/builds/5378
I'm reverting this entire commit so the bots aren't blocked on these
failures.
This reverts commit r215261.
