1869ac8b71 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 Parallel addition and subtraction, signed/unsigned
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]

baafcbb4db 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.

d30103dd36 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.

243296690e 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.

d4397b9481 finish off the factoring optimization along the lines of the
current design.  This generates a matcher that successfully
runs, but it turns out that the factoring we're doing violates
the ordering of patterns, so we end up matching (e.g.) movups
where we want movaps.  This won't due, but I'll address this in
a follow on patch.  It's nice to not be on by default yet! :)
