Daniel Dunbar 692d06fb77 MC: Fix bug where trailing tied operands were forgotten; the X86 assembler 
matcher is now free of implicit operands!
 - Still need to clean up the code now that we don't to worry about implicit
   operands, and to make it a hard error if an instruction fails to specify all
   of its operands for some reason.

Bob Wilson 0827e040e0 Add a new pass on machine instructions to optimize away PHI cycles that 
reduce down to a single value.  InstCombine already does this transformation
but DAG legalization may introduce new opportunities.  This has turned out to
be important for ARM where 64-bit values are split up during type legalization:
InstCombine is not able to remove the PHI cycles on the 64-bit values but
the separate 32-bit values can be optimized.  I measured the compile time 
impact of this (running llc on 176.gcc) and it was not significant.

Nate Begeman c780af6471 Add a missing pattern for movhps so that we get: 
movq	(%ecx,%edx,2), %xmm2
movhps	(%ecx,%eax,2), %xmm2

rather than:

movq     (%eax, %edx, 2), %xmm2		
movq     (%eax, %ebx, 2), %xmm3		
movlhps  %xmm3, %xmm2			

Testcase forthcoming.

Ted Kremenek e9711db487 Two changes to scan-build: 
(1) When no 'clang' is found with 'scan-build', remember the one from
the path as scan-build sees it, not the build system.  This prevents
us from finding different clangs during the build.

(2) Don't set LDPLUSPLUS when running xcodebuild; instead rely on the
clang driver to do the right thing.

Douglas Gregor 50dc219e8b When we have a dependent direct initializer but not a dependent 
variable type, we can (and should) still check for completeness of the
variable's type. Do so, to work around an assertion that shows up in
Boost's shared_ptr.

Douglas Gregor 7eeb59752a When AST merging for record declarations fails, warn about the 
incompatibility and show where the structural differences are. For
example:

struct1.c:36:8: warning: type 'struct S7' has incompatible definitions
in different translation units
struct S7 { int i : 8; unsigned j : 8; } x7;
       ^
struct1.c:36:33: note: bit-field 'j' with type 'unsigned int' and length 8 here
struct S7 { int i : 8; unsigned j : 8; } x7;
                                ^
struct2.c:33:33: note: bit-field 'j' with type 'unsigned int' and length 16 here
struct S7 { int i : 8; unsigned j : 16; } x7;
                                ^

There are a few changes to make this work:
  - ASTImporter now has only a single Diagnostic object, not multiple
  diagnostic objects. Otherwise, having a warning/error printed via
  one Diagnostic and its note printed on the other Diagnostic could
  cause the note to be suppressed.
  - Implemented import functionality for IntegerLiteral (along with
  general support for statements and expressions)
