d20c0bc569 don't emit useless functions. These were producing 
warnings in release-assert builds if there were no cases.

ff7fb60f2a enhance the EmitNode/MorphNodeTo operands to take a bit that 
specifies whether there is an output flag or not.  Use this
instead of redundantly encoding the chain/flag results in the
output vtlist.

is just a silly wrapper around MorphNodeTo.

c78f2a3994 enhance the new isel to use SelectNodeTo for most patterns, 
even some the old isel didn't.  There are several parts of
this that make me feel dirty, but it's no worse than the
old isel.  I'll clean up the parts I can do without ripping
out the old one next.

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.

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
us to use implied types for a broad range of nodes, even
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.
