Cameron Zwarich 2dffcebf77 To find the exiting VN of a LiveInterval from a block, use the previous slot
rather than the previous index. If a block has a single instruction, the
previous index may be in a different basic block.

I have no clue how this used to work on all of test-suite, because now this
failure is seen quite often when trying to compile code with -strong-phi-elim.
This fixes PR10252.

Douglas Gregor ebcfbb5d22 When we determine that a function template specialization produced as
part of template argument deduction is ill-formed, we mark it as
invalid and treat it as a deduction failure. If we happen to find that
specialization again, treat it as a deduction failure rather than
silently building a call to the declaration.

Fixes PR11117, a marvelous bug where deduction failed after creating
an invalid specialization, causing overload resolution to pick a
different candidate. Then we performed a similar overload resolution
later, and happily picked the invalid specialization to
call... resulting in a silent link failure.

Sean Callanan ca4e0fd7e6 Refactoring in preparation for having multiple
calls to the FindExternalVisibleDecls function.

FindExternalVisibleDecls was recording whether
it had found generic function symbols in variables
that were local to the function.  Now, however,
multiple calls occur in response to one request
from Clang, since we may be searching across
namespaces.  To support that, I moved the local
variables into a bitfield in NameSearchContext.

Bob Wilson 73a4deb33d Change __extension__ to disable only diagnostics controlled by -pedantic.
This changes clang to match GCC's behavior for __extension__, which temporarily
disables the -pedantic flag.  Warnings that are enabled without -pedantic
are not affected.  Besides the general goodness of matching GCC's precedent,
my motivation for this is that macros in the arm_neon.h header need to use
__extension__ to avoid pedantic complaints about their use of statement
expressions, yet we still want to warn about incompatible pointer arguments
for those macros.

Douglas Gregor 205d044552 Switch diagnostic text from "C++0x" over to "C++11".
We'd also like for "C++11" or "c++11" to be used for the warning
groups, but without removing the old warning flags. Patches welcome;
I've run out of time to work on this today.
