Reid Kleckner 52edddaea5 Add support for MSVC's __FUNCSIG__
It is very similar to GCC's __PRETTY_FUNCTION__, except it prints the
calling convention.

Reid Kleckner 6df5254d6f intrin.h: Fix up bugs in the cr3 and msr intrinsics
Don't include input and output regs in clobbers.  Prefix some
identifiers with __.  Add a memory constraint to __readcr3 to prevent
reordering.  This constraint is heavy handed, but conservatively
correct.

Thanks to PaX Team for the suggestions.

Daniel Jasper d74cf40386 clang-format: Extend AllowShortFunctions.. to only merge inline functions.
Before AllowShortFunctionsOnASingleLine could either be true, merging
all functions, or false, merging no functions. This patch adds a third
value "Inline", which can be used to only merge short functions defined
inline in a class, i.e.:

  void f() {
    return 42;
  }

  class C {
    void f() { return 42; }
  };

DeLesley Hutchins b2213910de Thread Safety Analysis: update to internal SExpr handling.
This patch is the first part of a significant refactoring that seeks to restore
sanity to way thread safety analysis deals with capability expressions.  The
current patch merely provides an outline of the structure of the new system.
It's not yet connected to the actual analysis, so there's no change in
functionality.

David Blaikie f1b382e87d DebugInfo: Support type alias templates

David Blaikie bb11391d04 DebugInfo: Avoid emitting constnants for every use

Richard Trieu f935b562b9 Add a new subgroup to -Wtautological-compare, -Wtautological-overlap-compare,
which warns on compound conditionals that always evaluate to the same value.
For instance, (x > 5 && x < 3) will always be false since no value for x can
satisfy both conditions.

This patch also changes the CFG to use these tautological values for better
branch analysis.  The test for -Wunreachable-code shows how this change catches
additional dead code.

Jordan Rose 8a5a094ec5 [analyzer] Look through temporary destructors when finding a region to construct.
Fixes a false positive when temporary destructors are enabled where a temporary

processed, which occurs when the variable is in the condition of an if or while.

David Blaikie a1556556d6 DebugInfo: PR19298: function local const variables duplicated in the root scope
See the comment for CodeGenFunction::tryEmitAsConstant that describes
how in some contexts (lambdas) we must not emit references to the
variable, but instead use the constant directly - because of this we end
up emitting a constant for the variable, as well as emitting the
variable itself.

Should we just skip putting the variable on the stack at all and omit
the debug info for the constant? It's not clear to me - what if the
address of the local is taken?

Justin Bogner f3aefca7c1 CodeGen: Don't create branch weight metadata from empty profiles
If all of our weights are zero when calculating branch weights, it

overload. These were already working.
