Chris Lattner c577b816fc Teach the grouper some simple tricks about looking contradictory
predicates.  For example if we have:

Scope:
  CheckType i32
    ABC
  CheckType f32
    DEF
  CheckType i32
    GHI

Then we know that we can transform this into:
Scope:
  CheckType i32
    Scope
      ABC
      GHI
  CheckType f32
    DEF

This reorders the check for the 'GHI' predicate above
the check for the 'DEF' predidate.  However it is safe to do this
in this situation because we know that a node cannot have both an
i32 and f32 type.

We're now doing more factoring that the old isel did.

Chris Lattner d9e1e83e3b implement a new optimization to sink pattern predicates (like isSSE1)
as deeply into the pattern as we can get away with.  In pratice, this 
means "all the way to to the emitter code, but not across 
ComplexPatterns".  This substantially increases the amount of factoring
we get.

Douglas Gregor b8b9f28e24 Robustify SourceManager::getLocation(), so that it returns an
end-of-line source location when given a column number beyond the
length of the line, or an end-of-file source location when given a
line number beyond the length of the file. Previously, we would return
an invalid location.

Douglas Gregor 89a56c561f When given unsaved files in clang_createTranslationUnitFromSourceFile,
copy the source buffers provided rather than referencing them
directly, so that the caller can free those buffers immediately after
calling clang_createTranslationUnitFromSourceFile(). Otherwise, we
risk hitting those buffers later (when building source ranges, forming
diagnostics, etc.).

Chris Lattner 65d3a0a5f8 Fix rdar://7694996 a miscompile of 183.equake from my patch yesterday,
confusing the old MAT variable with the new GlobalType one.  This caused
us to promote the @disp global pointer into:

@disp.body = internal global double*** undef

instead of:

@disp.body = internal global [3 x double**] undef

Bill Wendling c3a9376215 A much cleaner (and less code!) way of inserting the correct amount of padding
for alignment into the LSDA. If the TType base offset is emitted, then put the
padding there. Otherwise, put it in the call site table length. There will be no
conflict between the two sites when placing the padding in one place.

o Miscellaneous operations: QADD, QDADD, QSUB, QDSUB
o Unsigned sum of absolute differences [and accumulate]: USAD8, USADA8
o Signed/Unsigned saturate: SSAT, SSAT16, USAT, USAT16
o Signed multiply accumulate long (halfwords): SMLAL<x><y>
o Signed multiply accumulate/subtract [long] (dual): SMLAD[x], SMLALD[X], SMLSD[X], SMLSLD[X]
o Signed dual multiply add/subtract [long]: SMUAD[X], SMUSD[X]

Jakob Stoklund Olesen 17d54920d7 Merge PPC instructions FMRS and FMRD into a single FMR instruction.
This is possible because F8RC is a subclass of F4RC. We keep FMRSD around so
fextend has a pattern.

Also allow folding of memory operands on FMRSD.

Dan Gohman 94fa92b441 Improve the vim code for highlighting trailing whitespace and lines
longer than 80 columns. This replaces the heavy-handed "textwidth"
mechanism, and makes the trailing-whitespace highlighting lazy so
that it isn't constantly jumping on the user during typing.

Jakob Stoklund Olesen ddbf7a858e Use the right floating point load/store instructions in PPCInstrInfo::foldMemoryOperandImpl().
The PowerPC floating point registers can represent both f32 and f64 via the
two register classes F4RC and F8RC. F8RC is considered a subclass of F4RC to
allow cross-class coalescing. This coalescing only affects whether registers
are spilled as f32 or f64.

Spill slots must be accessed with load/store instructions corresponding to the
class of the spilled register. PPCInstrInfo::foldMemoryOperandImpl was looking
at the instruction opcode which is wrong.

X86 has similar floating point register classes, but doesn't try to fold
memory operands, so there is no problem there.
