456b33b615 Refactor the constant folding code into it's own function. And call it from both 
the SelectionDAG and DAGCombiner code. The only functionality change is that now
the DAG combiner is performing the constant folding for these operations instead
of being a no-op.

This is *not* in response to a bug, so there isn't a testcase.

bc29bec7f8 Next round of earlyclobber handling. Approach the 
RA problem by expanding the live interval of an
earlyclobber def back one slot.  Remove
overlap-earlyclobber throughout.  Remove 
earlyclobber bits and their handling from
live internals.

192b12c522 Now that ConstantSDNode doesn't hold an APInt, 
use ARG_FLAGSSDNode as the most aligned node type,
as it contains an int64_t, which is 8-byte
aligned on mingw.

b2b5ddfaf6 Remove the MarkModRef pass (use AddReadAttrs instead). 
Unfortunately this means removing one regression test
of GlobalsModRef because I couldn't work out how to
perform it without MarkModRef.

c2ff9ca568 Add a new pass AddReadAttrs which works out which functions 
can get the readnone/readonly attributes, and gives them it.
The plan is to remove markmodref (which did the same thing
by querying GlobalsModRef) and delete the analogous
functionality from GlobalsModRef.

b7c5b0f44b Add a new "fast" scheduler. This is currently basically just a 
copy of the BURRList scheduler, but with several parts ripped
out, such as backtracking, online topological sort maintenance
(needed by backtracking), the priority queue, and Sethi-Ullman
number computation and maintenance (needed by the priority
queue). As a result of all this, it generates somewhat lower
quality code, but that's its tradeoff for running about 30%
faster than list-burr in -fast mode in many cases.

This is somewhat experimental. Moving forward, major pieces of
this can be refactored with pieces in common with
ScheduleDAGRRList.cpp.

99091ed94f Add a bit to mark operands of asm's that conflict 
with an earlyclobber operand elsewhere.  Propagate
this bit and the earlyclobber bit through SDISel.
Change linear-scan RA not to allocate regs in a way 
that conflicts with an earlyclobber.  See also comments.
