Douglas Gregor 960b5bc7c1 Initial implementation of member name lookup

Daniel Dunbar 87cb84e9f0 ccc: Implement support clang PTH using gcc PCH style interface.
This requires some hackery, as gcc's PCH mechanism changes behavior,
whereas while PTH is simply a cache. Notably:

 - Automatically cause clang to load a .pth file if we find one that
   matches a command line -include argument (similar to how gcc
   looks for .gch files).

 - When generating precompiled headers, translate the suffix from .gch
   to .pth (so we do not conflict with actual gcc PCH files).

 - When generating precompiled headers, copy the input header to the
   same location as the output PTH file. This is necessary because gcc
   supports -include xxx.h even if xxx.h doesn't exist, but for clang
   we need to actually have the contents of this file available.

Douglas Gregor 3407432644 Refactor name lookup.
This change refactors and cleans up our handling of name lookup with
LookupDecl. There are several aspects to this refactoring:

  - The criteria for name lookup is now encapsulated into the class
  LookupCriteria, which replaces the hideous set of boolean values
  that LookupDecl currently has.

  - The results of name lookup are returned in a new class
  LookupResult, which can lazily build OverloadedFunctionDecls for
  overloaded function sets (and, eventually, eliminate the need to
  allocate member for OverloadedFunctionDecls) and contains a
  placeholder for handling ambiguous name lookup (for C++).

  - The primary entry points for name lookup are now LookupName (for
    unqualified name lookup) and LookupQualifiedName (for qualified
    name lookup). There is also a convenience function
    LookupParsedName that handles qualified/unqualified name lookup
    when given a scope specifier. Together, these routines are meant
    to gradually replace the kludgy LookupDecl, but this won't happen
    until after we have base class lookup (which forces us to cope
    with ambiguities).

  - Documented the heck out of name lookup. Experimenting a little
    with using Doxygen's member groups to make some sense of the Sema
    class. Feedback welcome!

  - Fixes some lingering issues with name lookup for
  nested-name-specifiers, which now goes through
  LookupName/LookupQualifiedName.

Richard Osborne 4359325ba8 Add pseudo instructions to the XCore for (load|store|load address) of a
frame index. eliminateFrameIndex will replace these instructions with
(LDWSP|STWSP|LDAWSP) or (LDW|STW|LDAWF) if a frame pointer is in use.

This fixes PR 3324. Previously we used LDWSP, STWSP, LDAWSP before frame
pointer elimination. However since they were marked as implicitly using
SP they could not be rematerialised.

Small cleanup in the handling of user-defined conversions. 

Also, implement an optimization when constructing a call. We avoid

conversion sequences that we computed as part of overload resolution.

Dale Johannesen 1f0e0e7c9c Fix the time regression I introduced in 464.h264ref with
my earlier patch to this file.

The issue there was that all uses of an IV inside a loop
are actually references to Base[IV*2], and there was one
use outside that was the same but LSR didn't see the base
or the scaling because it didn't recurse into uses outside
the loop; thus, it used base+IV*scale mode inside the loop
instead of pulling base out of the loop.  This was extra bad
because register pressure later forced both base and IV into
memory.  Doing that recursion, at least enough
to figure out addressing modes, is a good idea in general;
the change in AddUsersIfInteresting does this.  However,
there were side effects....

It is also possible for recursing outside the loop to
introduce another IV where there was only 1 before (if
the refs inside are not scaled and the ref outside is).
I don't think this is a common case, but it's in the testsuite.
It is right to be very aggressive about getting rid of
such introduced IVs (CheckForIVReuse and the handling of
nonzero RewriteFactor in StrengthReduceStridedIVUsers).
In the testcase in question the new IV produced this way
has both a nonconstant stride and a nonzero base, neither
of which was handled before.  And when inserting 
new code that feeds into a PHI, it's right to put such 
code at the original location rather than in the PHI's 
immediate predecessor(s) when the original location is outside 
the loop (a case that couldn't happen before)
(RewriteInstructionToUseNewBase); better to avoid making
multiple copies of it in this case.

Also, the mechanism for keeping SCEV's corresponding to GEP's
no longer works, as the GEP might change after its SCEV
is remembered, invalidating the SCEV, and we might get a bad
SCEV value when looking up the GEP again for a later loop.  
This also couldn't happen before, as we weren't recursing
into GEP's outside the loop.

Also, when we build an expression that involves a (possibly
non-affine) IV from a different loop as well as an IV from
the one we're interested in (containsAddRecFromDifferentLoop),
don't recurse into that.  We can't do much with it and will
get in trouble if we try to create new non-affine IVs or something.

More testcases are coming.

Ted Kremenek e9814186ac PTH:
- Use canonical FileID when using getSpelling() caching.  This
  addresses some cache misses we were seeing with -fsyntax-only on
  Cocoa.h
- Added Preprocessor::getPhysicalCharacterAt() utility method for
  clients to grab the first character at a specified sourcelocation.
  This uses the PTH spelling cache.
- Modified Sema::ActOnNumericConstant() to use
  Preprocessor::getPhysicalCharacterAt() instead of
  SourceManager::getCharacterData() (to get PTH hits).

These changes cause -fsyntax-only to not page in any sources from
Cocoa.h.  We see a speedup of 27%.
