11b219e461 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.

fbec6680d1 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.

3ff9f2d102 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.

1864d6728d 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.

c5ea87bca7 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.

b227ae4ddb reimplement support for GS and FS relative address space matching 
by having X86DAGToDAGISel::SelectAddr get passed in the parent node
of the operand match (the load/store/atomic op) and having it get
the address space from that, instead of having special FS/GS addr
mode operations that require duplicating the entire instruction set
to support.

This makes FS and GS relative accesses *far* more predictable and
work much better.  It also simplifies the X86 backend a bit, more
to come.

There is still a pending issue with nodes like ISD::PREFETCH and
X86ISD::FLD, which really should be MemSDNode's but aren't.

6543dacfac Rework passing parent pointers into complexpatterns, I forgot 
that complex patterns are matched after the entire pattern has
a structural match, therefore the NodeStack isn't in a useful
state when the actual call to the matcher happens.

a22747a563 Move a sign-extend or a zero-extend of a load to the same basic block as the 
load when the type of the load is not legal, even if truncates are not free.
