f7e8af925c Be more clever about regclasses in ScheduleDAGSDNodes::EmitCopyFromReg. 
If two uses of a CopyFromReg want different regclasses, first try a common
sub-class, then fall back on the copy emitted in AddRegisterOperand. There is
no need for an assert here. The cross-class joiner usually cleans up nicely.

69e973d79b CMake: Hopefully this will fix the build on VS. I can't replicate the 
failure with VS 9.0, nmake and cmake 2.6.4. The buildbot output does
not show the patch level of cmake, it just says 2.6.

Sadly, parallel builds are broken due to recent changes on LLVM Target
libraries and its auxiliaries (TargetInfo, AsmPrinter, AsmParser). I
have a patch for stablishing the correct dependencies, but cmake is
buggy and generates makefiles that can't handle them.

12bb766ae9 Fix for PR3016: detect the tricky case, where there are 
unfoldable references to a PHI node in the block being folded, and disable
the transformation in that case.  The correct transformation of such PHI
nodes depends on whether BB dominates Succ, and dominance is expensive 
to compute here.  (Alternatively, it's possible to check whether any 
uses are live, but that's also essentially a dominance calculation. 
Another alternative is to use reg2mem, but it probably isn't a good idea to
use that in simplifycfg.)

Also, remove some incorrect code from CanPropagatePredecessorsForPHIs 
which is made unnecessary with this patch: it didn't consider the case 
where a PHI node in BB has multiple uses.

30c74a2429 implement support for lowering references to global addresses. For example, we now 
can asmprint:

NEW: 	movl	"L___stack_chk_guard$non_lazy_ptr", %eax
OLD: 	movl	L___stack_chk_guard$non_lazy_ptr, %eax

where 'new' is coming out of the MCInst version of the printer.

3f5bb168bc An overhaul of the exception handling code. This is arguably more correct than 
what was there before. In "no FP mode", we weren't generating labels and unwind
table entries after each "push" instruction. While more than likely "okay", it's
not technically correct. The major thing was that the ordering of when to define
a new CFA register and at what offset wasn't correct. This would cause the
exception handling to fail in ways most miserable to users.

I also cleaned up some code a bit. There's one function which has a "return" at
the beginning, so it's never used. Should I just remove it? :-)
