b0cf049a1e Generalize ScalarEvolution to be able to analyze GEPs when 
TargetData is not present. It still uses TargetData when available.
This generalization also fixed some limitations in the TargetData
case; the attached testcase covers this.

896c999947 CMake: LLVM_ENABLE_PIC now defaults to ON, as in `configure'. This is 
required on some platforms for building shared libraries that link to
the LLVM libraries.

5022dd9cc9 Make tail merging handle blocks with repeated predecessors correctly, and 
remove RemoveDuplicateSuccessor, as it is no longer necessary, and because
it breaks assumptions made in
MachineBasicBlock::isOnlyReachableByFallthrough.

Convert test/CodeGen/X86/omit-label.ll to FileCheck and add a testcase
for PR4732.

test/CodeGen/Thumb2/thumb2-ifcvt2.ll sees a diff with this commit due to
it being bugpoint-reduced to the point where it doesn't matter what the
condition for the branch is.

Add some more interesting code to
test/CodeGen/X86/2009-08-06-branchfolder-crash.ll, which is the testcase
that originally motivated the RemoveDuplicateSuccessor code, to help
verify that the original problem isn't being re-broken.

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.

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.
