Evan Cheng 54c13da29c Added preliminary x86 subtarget support.

Duraid Madina 0ebb0b1c5c fix stack corruption! Previously, 16-byte whole-FP-register stores were
being treated as needing only 8 bytes (though they were 16 byte aligned.)

This should fix a bunch of tests - anyone have any comments, though?

  - in Target.td , SpillSize and SpillAlignment seem dead - is this what
    Size and Alignment do now?
  - in CodeGenRegisters.h/CodeGenTarget.cpp , DeclaredSpillSize and
    DeclaredSpillAlignment seem dead.
  - there are a bunch of comments here and there that don't clearly
    distinguish between 'size' and 'spillsize' etc. hmm.

Evan Cheng 944d1e91ea When trying to fold X86::SETCC into a Select, make a copy if it has more than
one use. This allows more CMOV instructions.

Evan Cheng c4c339c3d0 Clean up some code; improve efficiency; and fixed a potential bug involving
chain successors.

Evan Cheng 97c68f0f5c Remove the uses of STATUS flag register. Rely on node property SDNPInFlag,
SDNPOutFlag, and SDNPOptInFlag instead.

Evan Cheng ecfaa0a1c9 Incoming (and optional) flag bugs. They may be embedded inside a inner node of
a pattern. Also, nodes which take incoming flag should not be folded if it has
more than one use.

Evan Cheng 1880f8db02 No need to keep track of top and bottom nodes in a group since the vector is
already in order. Thanks Jim for pointing it out.

Evan Cheng a6eff8a432 If scheduler choice is the default (-sched=default), use target scheduling
preference to determine which scheduler to use. SchedulingForLatency ==
Breadth first; SchedulingForRegPressure == bottom up register reduction list
scheduler.
