6d9b38bd58 Fix Triple to recognize the 'bfin' arch.

b82fc63e02 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.

7a382434b5 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.

178666f2e3 add support for some targetflags on GV operands. This allows us to 
send instructions like:

NEW: 	movl	"L___stack_chk_guard$non_lazy_ptr" - "L1$pb"(%esi), %eax
OLD: 	movl	L___stack_chk_guard$non_lazy_ptr-"L1$pb"(%esi), %eax

through the streamer.  Several fixmes.

c9d9a008b5 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.

Patch by Sandeep Patel!

ff6e66e502 PowerPC inline asm was emitting two output operands 
for a single "m" constraint; this is wrong because the
opcode of a load or store would have to change in parallel.
This patch makes it always compute addresses into a register,
which is correct but not as efficient as possible.  7144566.

4643e96d36 Move the sjlj exception handling conversions to a back-end pass where they 
more properly belong. This allows removing the front-end conditionalized
SJLJ code, and cleans up the generated IR considerably. All of the
infrastructure code (calling _Unwind_SjLj_Register/Unregister, etc) is
added by the SjLjEHPrepare pass.

d0eda03882 Don't access the first element of a potentially empty 
vector (&Formals[0]).  With this change llvm-gcc builds
with expensive checking enabled for C, C++ and Fortran.
While there, change a std::vector into a SmallVector.
This is partly gratuitous, but mostly because not all
STL vector implementations define the data method (and
it should be faster).

fc68e5368b change AsmPrinter to switch sections using AsmStreamer instead of 
doing it directly.  This requires const'izing a bunch of stuff that
took sections, but this seems like the right semantic thing to do:
emitting a label to a section shouldn't mutate the MCSection object
itself, for example.
