Handle AddrMode4 for Thumb2 in rewriteT2FrameIndex. This occurs for
...
VLDM/VSTM instructions, and without this check, the code assumes that an
offset is allowed, as it would be with VLDR/VSTR. The asm printer,
however, silently drops the offset, producing incorrect code. Since the
address register in this case is either the stack or frame pointer, the
spill location ends up conflicting with some other stack slot or with
outgoing arguments on the stack.

remove DebugLoc from MCInst and eliminate "Comment printing" from
...
the MCInst path of the asmprinter. Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter. This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.
This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

hoist the call to processDebugLoc out of the generated

asm printer into the "printInstruction" routine. This
fixes a problem where the experimental asmprinter would

It is annoying that this moves the call from one place into each
target, but a future set of more invasive refactorings will fix
that problem.

This patch takes pain to ensure all the PEI lowering code does the right thing when lowering frame indices, insert code to manipulate stack pointers, etc. It's also custom lowering dynamic stack alloc into pseudo instructions so we can insert the right instructions at scheduling time.

Major calling convention code refactoring.
...
Instead of awkwardly encoding calling-convention information with ISD::CALL,
ISD::FORMAL_ARGUMENTS, ISD::RET, and ISD::ARG_FLAGS nodes, TargetLowering
provides three virtual functions for targets to override:
LowerFormalArguments, LowerCall, and LowerRet, which replace the custom
lowering done on the special nodes. They provide the same information, but
in a more immediately usable format.
This also reworks much of the target-independent tail call logic. The
decision of whether or not to perform a tail call is now cleanly split
between target-independent portions, and the target dependent portion
in IsEligibleForTailCallOptimization.
This also synchronizes all in-tree targets, to help enable future
refactoring and feature work.

Don't flush the raw_ostream between each MachineFunction. These flush
...
calls were originally put in place because errs() at one time was
not unbuffered, and these print routines are commonly used with errs()
for debugging. However, errs() is now properly unbuffered, so the
flush calls are no longer needed. This significantly reduces the
number of write(2) calls for regular asm printing when there are many
small functions.

Rip all of the global variable lowering logic out of TargetAsmInfo. Since
...
it is highly specific to the object file that will be generated in the end,
this introduces a new TargetLoweringObjectFile interface that is implemented
for each of ELF/MachO/COFF/Alpha/PIC16 and XCore.
Though still is still a brutal and ugly refactoring, this is a major step
towards goodness.
This patch also:
1. fixes a bunch of dangling pointer problems in the PIC16 backend.
2. disables the TargetLowering copy ctor which PIC16 was accidentally using.
3. gets us closer to xcore having its own crazy target section flags and
pic16 not having to shadow sections with its own objects.
4. fixes wierdness where ELF targets would set CStringSection but not
CStringSection_. Factor the code better.
5. fixes some bugs in string lowering on ELF targets.

Change Thumb2 jumptable codegen to one that uses two level jumps:
...
Before:
adr r12, #LJTI3_0_0
ldr pc, [r12, +r0, lsl #2 ]
LJTI3_0_0:
.long LBB3_24
.long LBB3_30
.long LBB3_31
.long LBB3_32
After:
adr r12, #LJTI3_0_0
add pc, r12, +r0, lsl #2
LJTI3_0_0:
b.w LBB3_24
b.w LBB3_30
b.w LBB3_31
b.w LBB3_32
This has several advantages.
1. This will make it easier to optimize this to a TBB / TBH instruction +
(smaller) table.
2. This eliminate the need for ugly asm printer hack to force the address
into thumb addresses (bit 0 is one).
3. Same codegen for pic and non-pic.
4. This eliminate the need to align the table so constantpool island pass
won't have to over-estimate the size.
Based on my calculation, the later is probably slightly faster as well since
ldr pc with shifter address is very slow. That is, it should be a win as long
as the HW implementation can do a reasonable job of branch predict the second
branch.

Revert 75762, 75763, 75766..75769, 75772..75775, 75778, 75780, 75782 to repair broken LLVM-GCC build.
...
Will revert 75770 in the llvm-gcc trunk.

Replace large swaths of copy-n-paste code with obvious helper function...
...
- Which was already present in the module!
- I skipped this xform for Alpha, since it runs an extra pass during assembly
emission, but not when emitting assembly via the DumpAsm flag.
- No functionality change.

Provide TargetMachine implementations with reference to Target they were created
...
from.
- This commit is almost entirely propogating the reference through the
TargetMachine subclasses' constructor calls.

Register Target's TargetMachine and AsmPrinter in the new registry.
...
- This abuses TargetMachineRegistry's constructor for now, this will get
cleaned up in time.

Add TargetInfo libraries for all targets.

- Intended to match current TargetMachine implementations.
- No facilities for linking these in yet.

doing it with printSuffixedName.

fix an arm codegen bug (the same as PR4482 on ppc) where available_externally

symbols were not getting stubs. While I'm at it, add a big testcase for
stub generation to make sure I don't break anything.

printSuffixedName.
