only existed as the result of a misunderstanding.

David Greene 20a1cbefad [AVX] Add decode support for VUNPCKLPS/D instructions, both 128-bit
and 256-bit forms.  Because the number of elements in a vector
      does not determine the vector type (4 elements could be v4f32 or
      v4f64), pass the full type of the vector to decode routines.

Argyrios Kyrtzidis 2c49ec7f1d [analyzer] Migrate NSErrorChecker and DereferenceChecker to CheckerV2.
They cooperate in that NSErrorChecker listens for ImplicitNullDerefEvent events that
DereferenceChecker can dispatch.
ImplicitNullDerefEvent is when we dereferenced a location that may be null.

Argyrios Kyrtzidis a15dfec3f5 [analyzer] Introduce "event" mechanism in CheckerManager.
A checker can register as receiver/listener of "events" (basically it registers a callback
with a function getting called with an argument of the event type) and other checkers can
register as "dispatchers" and can pass an event object to all the listeners.
This allows cooperation amongst checkers but with very loose coupling.

Douglas Gregor 5a064725d6 Eliminate the last remains of TemplateSpecializationTypes with
dependent template names. There is still a lot of redundant code in
TreeTransform to cope with TemplateSpecializationTypes, which I'll
remove in stages.

David Chisnall da20991a1b Make -fobjc-nonfragile-abi and -fgnu-runtime imply -fblocks (unless -fno-blocks is specified), because this combination of flags defines an Objective-C runtime that includes a blocks runtime.

Kalle Raiskila 612b85e58c Add branch hinting for SPU.
The implemented algorithm is overly simplistic (just speculate all branches are
taken)- this is work in progress.

Axel Naumann aa627ba724 From Vassil Vassilev:
* Add default implementations (no-op) for ExternalASTSource's pure virtual functions. There are valid use cases that can live with these defaults.
* Move ExternalASTSource's out of line implementations into separate source file.
* Whitespace, forward decl, #include cleanup.

Nick Lewycky 66f4f22f7b srem doesn't actually have the same resulting sign as its numerator, you could
also have a zero when numerator = denominator. Reverts parts of r126635 and
r126637.

Chandler Carruth 306f98c241 Add a test case that would have caught the bug fixed in r126640.
I've only covered C++'s flags here, we should probably do something
similar for ObjC flags.

Chandler Carruth 74f8711802 Fix a tiny goof in the Driver's logic which caused the explicit presence
of -fexceptions to disably C++ exceptions. The correct code was in the
ObjC branch, this just mirrors that logic on the C++ side of things.
Thanks to John Wiegley for pointing this out.

Che-Liang Chiou 75a800d3bf Add preliminary support for .f32 in the PTX backend.
- Add appropriate TableGen patterns for fadd, fsub, fmul.
- Add .f32 as the PTX type for the LLVM float type.
- Allow parameters, return values, and global variable declarations
  to accept the float type.
- Add appropriate test cases.

Nick Lewycky 6b445419b0 The sign of an srem instruction is the sign of its dividend (the first

Peter Collingbourne 2f1e36bfd0 Rename tok::eom to tok::eod.
The previous name was inaccurate as this token in fact appears at
the end of every preprocessing directive, not just macro definitions.
No functionality change, except for a diagnostic tweak.

Anders Carlsson e96ab55b28 Add a -fcxx-exceptions flag to the frontend, which can be used to enable
C++ exceptions, even when exceptions have been turned off using -fno-exceptions.
Make the -fobjc-exceptions flag do the same thing, but for Objective-C exceptions.

C++ and Objective-C exceptions can also be disabled using -fno-cxx-excptions and
-fno-objc-exceptions.

Ken Dyck 1b4420ed42 Retry r126357. Use CharUnits for the Size and DataSize calculations when
they are known to be exact multiples of the width of the char type. Add a
test case to CodeGen/union.c that would have caught the problem with the
previous attempt. No change in functionality intended.
