Richard Smith 31ce793a0b Rename -Wc++0x-compat, -Wc++0x-extensions and -Wc++0x-narrowing from c++0x to
c++11. The old names are kept for backwards-compatibility. Patch by Ahmed
Charles! Names for backwards-compatible DiagGroups removed by me.

Jeffrey Yasskin a722170eb9 Implement the first piece of a -Wc++98-compat flag so that people can build in
C++11 mode but keep their sources compatible with C++98.  This patch implements
the -Wc++98-compat-variadic-templates sub-flag and -Wc++98-compat to include
it.

Eric Christopher 7cdf948601 Recommit:
Start handling debug line and scope information better:

    Migrate most of the location setting within the larger API in CGDebugInfo and
    update a lot of callers.
    Remove the existing file/scope change machinery in UpdateLineDirectiveRegion
    and replace it with DILexicalBlockFile usage.

    Finishes off the rest of rdar://10246360

after fixing a few bugs that were exposed in gdb testsuite testing.

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.

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.

John McCall 50a2c2c19d Catch placeholder types in DefaultLvalueConversion
and DefaultFunctionArrayLvalueConversion.  To prevent
significant regression for should-this-be-a-call fixits,
and to repair some such regression from the introduction of
bound member placeholders, make those placeholder checks
try to build calls appropriately.  Harden the build-a-call
logic while we're at it.

Daniel Dunbar 0f41eee2a0 Driver: Add support for a new -nostdlibinc option.
- This disables the system include directories, but not the compiler builtin
   directories. Useful for projects that want to use things like the intrinsic
   headers, but are otherwise freestanding.

 - I'm willing to reconsider the option naming, I also considered providing an
   explicit -builtinc (which would match -nobuiltininc), but this is more
   consistent with existing options.
