165e96bd25 Properly clear all the extra bits in a significand when making a NaN from an
APInt.  Be certain to set the integer bit in an x87 extended-precision
significand so that we don't accidentally make a pseudo-NaN.

1e7ad3993d Add an override to StringRef::getAsInteger which parses into an APInt.
It gets its own implementation totally divorced from the (presumably
performance-sensitive) routines which parse into a uint64_t.

Add APInt::operator|=(uint64_t), which is situationally much better than
using a full APInt.

e12b73816b Teach APFloat how to create both QNaNs and SNaNs and with arbitrary-width

instead of sometimes making QNaNs and sometimes SNaNs depending on the
type.

225798143d Generalize my hack to use SDNodeInfo to find out when a
node is always guaranteed to have a particular type 
instead of hacking in ISD::STORE explicitly.  This allows

target specific ones.

874cadaf21 Implement XMM subregs.
Extracting the low element of a vector is now done with EXTRACT_SUBREG,
and the zero-extension performed by load movss is now modeled with
SUBREG_TO_REG, and so on.

Register-to-register movss and movsd are no longer considered copies;
they are two-address instructions which insert a scalar into a vector.

a363a9b71a Don't unconditionally suppress hoisting of instructions with implicit
defs or uses. The regular def and use checking below covers them, and
can be more precise. It's safe to hoist an instruction with a dead
implicit def if the register isn't live into the loop header.

9fa200d2a2 remove a bogus pattern, which had the same pattern as STDU
but codegen'd differently.  This really wanted to use some
sort of subreg to get the low 4 bytes of the G8RC register
or something.  However, it's invalid and nothing is testing
it, so I'm just zapping the bogosity.

82781b938a 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.

d323fd45e3 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.
