Chandler Carruth bbf65b0501 Remove the NameQualifier struct, which was just a wrapper around
NestedNameSpecifierLoc. It predates when we had such an object.

Reference the NNSLoc directly in DREs, and embed it directly into the
MemberNameQualifier struct.

Chandler Carruth e68f261dea Several cosmetic changes, no functionality changed.
Mostly trailing whitespace so that me editor nuking it doesn't muddy the
waters of subsequent commits that do change functionality.

Also nukes a stray statement that was harmless but redundant that
I introduced in r130666.

Chandler Carruth 0e439960b8 Move the state bits in DeclRefExpr out of the pointer union and into
a bitfield in the base class. DREs weren't using any bits here past the
normal Expr bits, so we have plenty of room. This makes the common case
of getting a Decl out of a DRE no longer need to do any masking etc.

Also, while here, clean up code to use the accessor methods rather than
directly poking these bits, and provide a nice comment for DREs that
includes the information previously attached to the bits going into the
pointer union.

No functionality changed here, but DREs should be a tad faster now.

Chandler Carruth c5276e584e Have the array type traits build an expression with type 'size_t'
instead of 'int'.

The Embarcadero spec says 'unsigned int', not 'int'. That's what
'size_t' is on Windows, but for Clang using a 'size_t' that can be
larger than int seems more appropriate.

Chandler Carruth 0d1a54f8e1 Remove more dead code for emitting diagnostics. The callers of these
functions already precluded dependent types from reaching them.

Also change one of the callers to not error when a trait is applied to
a dependent type. This is a perfectly reasonable pattern, and both Unary
and Binary type traits already support dependent types (by populating
the AST with a nonce value).

Remove the actual diagnostic, since these aren't errors.

Chandler Carruth 20b9bc8638 Convert the expression trait evaluation to a static function and

Chandler Carruth f2f5652d3d Remove the type traits UTT_IsLvalueExpr and UTT_IsRvalueExpr.
As might be surmised from their names, these aren't type traits, they're
expression traits. Amazingly enough, they're expression traits that we
have, and fully implement. These "type" traits are even parsed from the
same tokens as the expression traits. Luckily, the parser only tried the
expression trait parsing for these tokens, so this was all just a pile
of dead code.

Alexis Hunt 61bc173784 Fully implement delegating constructors!
As far as I know, this implementation is complete but might be missing a
few optimizations. Exceptions and virtual bases are handled correctly.

Because I'm an optimist, the web page has appropriately been updated. If
I'm wrong, feel free to downgrade its support categories.

Chandler Carruth 8e172c6054 More cleanup of the type traits implementation.
1) Moved the completeness checking routine above the evaluation routine
   so the reader sees that we do in fact check for complete types when
   necessary.
2) Remove the FIXME comment about not doing this.
3) Make the arguments to the evaluate function agree in order with those
   to the completeness checking function.
4) Completely specify the enumerators for the completeness checking
   function rather than relying on a default.
5) Remove a check for the Borland language to only require complete
   types in a few places. Borland's own documentation doesn't agree with
   this: some of the previously unspecified traits *do* require
   a complete type, some don't.
6) Correctly split the traits which do not require complete types from
   those that do, clarifying comments and citations to the standard or
   other documentation where relevant.

Chandler Carruth dde65ea89a Switch the interface name for both TemplateTypeParmType and
SubstTemplateTypeParmType to be 'getIdentifier' instead of 'getName' as
it returns an identifier. This makes them more consistent with the
NamedDecl interface.

Also, switch back to using this interface to acquire the indentifier in
TypePrinter.cpp. I missed this in r130628.

Chandler Carruth 0883632acb Re-applies the patch first applied way back in r106099, with
accompanying fixes to make it work today.

The core of this patch is to provide a link from a TemplateTypeParmType
back to the TemplateTypeParmDecl node which declared it. This in turn
provides much more precise information about the type, where it came
from, and how it functions for AST consumers.

To make the patch work almost a year after its first attempt, it needed
serialization support, and it now retains the old getName() interface.
Finally, it requires us to not attempt to instantiate the type in an
unsupported friend decl -- specifically those coming from template
friend decls but which refer to a specific type through a dependent
name.

A cleaner representation of the last item would be to build
FriendTemplateDecl nodes for these, storing their template parameters
etc, and to perform proper instantation of them like any other template
declaration. They can still be flagged as unsupported for the purpose of
access checking, etc.

This passed an asserts-enabled bootstrap for me, and the reduced test
case mentioned in the original review thread no longer causes issues,
likely fixed at somewhere amidst the 24k revisions that have elapsed.

Jakob Stoklund Olesen 2348cdd67f X86AsmPrinter doesn't know how to handle the X86II::MO_GOT_ABSOLUTE_ADDRESS flag
after folding ADD32ri to ADD32mi, so don't do that.

This only happens when the greedy register allocator gets itself in trouble and
spills %vreg9 here:

16L             %vreg9<def> = MOVPC32r 0, %ESP<imp-use>; GR32:%vreg9
48L             %vreg9<def> = ADD32ri %vreg9, <es:_GLOBAL_OFFSET_TABLE_>[TF=1], %EFLAGS<imp-def,dead>; GR32:%vreg9

That should never happen, the live range should be split instead.

Rafael Espindola 5265bc483e Enable CFI on OS X.
Currently the output should be almost identical to the one produced by CodeGen
to make the transition easier.

The only two differences I know of are:

* Some files get an extra advance loc of size 0. This will be fixed when
relaxations are enabled.
* The optimization of declaring an EH symbol as an external variable is not
implemented. This is a subset of adding the nounwind attribute, so we if really
this at -O0 we should probably do it at the IL level.
