b68987e4bf Change VDUPLANE DAG combiner to just return the result instead of calling 
CombineTo to avoid putting the result on the worklist.  I don't think it makes
much difference for now, but it might help someday as we add more DAG
combine optimizations.

0b8ccb8252 Combine both VMOVDRR(VMOVRRD) and VMOVRRD(VMOVDRR), instead of just doing one 
of those.  Refactor to share code for handling BUILD_VECTOR(VMOVRRD).
I don't have a testcase that exercises this, but it seems like an obvious
good thing to do.

ec57a1acec When moving zext/sext to be folded with a load, ignore the issue of whether 
truncates are free only in the case where the extended type is legal but the
load type is not.  If both types are illegal, such as when they are too big,
the load may not be legalized into an extended load.

eafca4e2b2 Attempt to fix llvm-gcc build. It was crashing when building gcov.o for an 
ARM cross-compiler on x86, because the MMO size did not match the type size.
This fixes the MMO size and also the size of the stack object to match the
type size.

1eb1b68e3a Fix an inconsistency in the x86 backend that led it to reject "calll foo" on 
x86-32: 32-bit calls were named "call" not "calll".  64-bit calls were correctly
named "callq", so this only impacted x86-32.

This fixes rdar://8456370 - llvm-mc rejects 'calll'

This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call,
I will file a bugzilla.

5fa42a45a1 Build the complement interval dupli after the split intervals instead of 
creating it before and subtracting split ranges.

This way, the SSA update code in LiveIntervalMap can properly create and use new
phi values in dupli. Now it is possible to create split regions where a value
escapes along two different CFG edges, creating phi values outside the split
region.

This is a work in progress and probably quite broken.
