Make AsmStreamer maintain a notion of the current section, pushing it up from the
MCAsmStreamer.  Based on this, eliminate the current section from AsmPrinter.

While I'm at it, clean up the last of the horrible "switch to null section" stuff
and add an assert.  This change is in preparation for completely eliminating
asmprinter::switchtosection.

add a horrible hack to the dwarf printer.  It looks like mingw is not specifying
an EHFrame section, so we just emit ehframe data into a random section.

This is clearly bad.

The attached patches attempt to fix cross builds. For example, if you
try to use i686-darwin to build for arm-eabi, you'll quickly run into
several false assumptions that the target OS must be the same as the
host OS. These patches split $(OS) into $(HOST_OS) and $(TARGET_OS) to
help builds like "make check" and the test-suite able to cross
compile. Along the way a target of *-unknown-eabi is defined as
"Freestanding" so that TARGET_OS checks have something to work with.

Fix the MSVC build again.

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.

CMake: Revert r79144. It reverted a change necessary for correct
parallel builds.

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.

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.

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? :-)
