d64b5c82b9 Add a argument to storeRegToStackSlot and storeRegToAddr to specify whether
the stored register is killed.

b97aec663b Add parameter to getDwarfRegNum to permit targets
to use different mappings for EH and debug info;
no functional change yet.

f191c80cd7 Use TableGen to emit information for dwarf register numbers.
This makes DwarfRegNum to accept list of numbers instead.
Added three different "flavours", but only slightly tested on x86-32/linux.
Please check another subtargets if possible,

66f0f64082 - Added a few target hooks to generate load / store instructions from / to any
address (not just from / to frameindexes).
- Added target hooks to unfold load / store instructions / SDNodes into separate
load, data processing, store instructions / SDNodes.

2365f51ed0 Long live the exception handling!
This patch fills the last necessary bits to enable exceptions
handling in LLVM. Currently only on x86-32/linux.

In fact, this patch adds necessary intrinsics (and their lowering) which
represent really weird target-specific gcc builtins used inside unwinder.

After corresponding llvm-gcc patch will land (easy) exceptions should be
more or less workable. However, exceptions handling support should not be 
thought as 'finished': I expect many small and not so small glitches
everywhere.

69d39091fe Two changes:
1. Treat FMOVD as a copy instruction, to help with coallescing in V9 mode
2. When in V9 mode, insert FMOVD instead of FpMOVD instructions, as we don't
   ever rewrite FpMOVD instructions into FMOVS instructions, thus we just end
   up with commented out copies!
This should fix a bunch of failures in V9 mode on sparc.

171049d10f * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.
* Added a pseudo instruction (for each target) that represent "return void".
  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)

85e42b45ac Reserve G1 for frame offset stuff and use it to handle large stack frames.
For example, instead of emitting this:

test:
        save -40112, %o6, %o6   ;; imm too large
        add %i6, -40016, %o0    ;; imm too large
        call caller
        nop
        restore %g0, %g0, %g0
        retl
        nop

emit this:

test:
        sethi 4194264, %g1
        or %g1, 848, %g1
        save %o6, %g1, %o6
        sethi 4194264, %g1
        add %g1, %i6, %g1
        add %i1, 944, %o0
        call caller
        nop
        restore %g0, %g0, %g0
        retl
        nop

which doesn't cause the assembler to barf.
