Douglas Gregor 0aa91e0a66 When inferring the result type of a block based on a return statement 
with a type-dependent expression, infer the placeholder type
'Context.DependentTy' to indicate that this is just a
placeholder. Fixes PR9982 / <rdar://problem/9486685>.

Eli Friedman 6ffb623a52 Match llvm-gcc's string literals alignment by forcing alignment on string literals to 1. This can significantly impact the size of the string data, and as far as I know, the alignment doesn't help performance. rdar://9078969 .

Fariborz Jahanian 7bd3d1c49b Patch to fix IR-gen crash generating structure ABI which implements 
user specified string class via -fconstant-string-class option.

John McCall 9dc0db2192 Use arrays and SmallVectors instead of std::vectors when building function 
types.  Also, cache a translation of 'void' in CGM and provide a ptrdiff_t
alias.  No functionality change.

mangled to avoid doing it twice for platforms that use prefixes like
Darwin.

Douglas Gregor 61226d3fcf When determining whether we can make a declaration into a global 
constant, also consider whether it's a class type that has any mutable
fields. If so, it can't be a global constant.

Douglas Gregor 2d1c055eba In C++, allow us to emit a global as 'constant' even if it has class 
type, so long as it is known to have a constant initializer and the
class type is a POD class. Fixes <rdar://problem/9306265>.

Alexis Hunt 4a8ea1092a Modify some deleted function methods to better reflect reality: 
- New isDefined() function checks for deletedness
 - isThisDeclarationADefinition checks for deletedness
 - New doesThisDeclarationHaveABody() does what
   isThisDeclarationADefinition() used to do
 - The IsDeleted bit is not propagated across redeclarations
 - isDeleted() now checks the canoncial declaration
 - New isDeletedAsWritten() does what it says on the tin.
 - isUserProvided() now correct (thanks Richard!)

This fixes the bug that we weren't catching

void foo() = delete;
void foo() {}

as being a redefinition.

Eli Friedman 49a94b1c7c Add an implementation of thunks for varargs methods. The implementation is a bit messy, but it is correct as long as the method in question doesn't use indirect gotos. A couple of possible alternative implementations are outlined in FIXME's in this patch. rdar://problem/8077308 .

Nick Lewycky 85c011ddc4 Preserve the full name of the file, so that '-c -o foo.pic.o' produces 
foo.pic.gcno instead of foo.gcno.

Francois Pichet 1c229c0472 Add -fdelayed-template-parsing option. Using this option all templated function definitions are parsed at the end of the translation unit only if it is required by an actual instantiation. As such all the symbols of the TU are available during name lookup. 
Using this flag is necessary for compatibility with Microsoft template code.
This also provides some parsing speed improvement.

Nick Lewycky 207bce31e1 Wire up the -ftest-coverage and -fprofile-arcs flags to .gcno file emission (at 
compile time) and .gcda emission (at runtime). --coverage enables both.

This does not yet add the profile_rt library to the link step if -fprofile-arcs
is enabled when linking.

Daniel Dunbar 9c8cd4c097 IRgen/Obj-C: Emit CFStrings and NSStrings with the alignment of the char type, 
there is no reason to align them higher.
 - This roughly matches llvm-gcc's r126913.
 - It is an open question whether or not we should do this for cstring's in
   general (code size vs optimization potential), for now we just match llvm-gcc
   until someone wants to run some experiments.

John McCall a97f329869 Template static data members can have weak_odr linkage, not just 
weak linkage.  Also, fix a problem where global weak variables
with non-trivial initializers were getting guard variables, or at
least were checking for them and then crashing.

John McCall 2979fe01da After some discussion with Doug, we decided that it made a lot more sense 
for __unknown_anytype resolution to destructively modify the AST.  So that's
what it does now, which significantly simplifies some of the implementation.
Normal member calls work pretty cleanly now, and I added support for
propagating unknown-ness through &.
