255f89faee Sort the #include lines for the include/... tree with the script.
AKA: Recompile *ALL* the source code!

This one went much better. No manual edits here. I spot-checked for
silliness and grep-checked for really broken edits and everything seemed
good. It all still compiles. Yell if you see something that looks goofy.

21739c1c72 Add a "PadTo" field to the emitULEB128Bytes method. This will pad out to the
indicated number of bytes.

47639fc5be The JIT calls TidyLandingPads to tidy up the landing pads. However, because the
JIT doesn't use the MC back-end asm printer to emit labels that it uses, the
section for the MCSymbol is never set. And thus the MCSymbol for the EH label
isn't marked as "defined". Because of that, TidyLandingPads removes the needed
landing pads from the JIT output. This breaks EH for every JIT program.

This is a work-around for this limitation. We pass in the label locations
map. If the label has a non-zero value, then it was "emitted" by the JIT and
TidyLandingPads shouldn't remove that label.

A nicer solution would be to mark the MCSymbol as "used" by the JIT and not rely
upon the section being set to determine if it's defined or not.

1611273351 change EH related stuff (other than EH_LABEL) to use MCSymbol
instead of label ID's.  This cleans up and regularizes a bunch 
of code and makes way for future progress.

Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
is largely copy and paste from DwarfException/MachineModuleInfo
and other places.  This is very sad and disturbing. :(

One major change here is that TidyLandingPads moved from being
called in DwarfException::BeginFunction to being called in
DwarfException::EndFunction.  There should not be any 
functionality change from doing this, but I'm not an EH expert.

32d7e6ebde Change indirect-globals to use a dedicated allocIndirectGV. This lets us
remove start/finishGVStub and the BufferState helper class from the
MachineCodeEmitter interface.  It has the side-effect of not setting the
indirect global writable and then executable on ARM, but that shouldn't be
necessary.

0261d795f8 Allow more than one stub to be being generated at the same time.
It's probably better in the long run to replace the
indirect-GlobalVariable system. That'll be done after a subsequent
patch.

01248e6711 Fix a bug where the DWARF emitter in the JIT was not initializing alignment
bytes.  libgcc doesn't seem to mind, but if you pass this DWARF to GDB, it
doesn't like it.  

Also make the JIT memory manager to initialize it's memory to garbage in debug
mode, so that it's easier to find bugs like these in the future.

e55fef36a9 1) Proper emit displacements for x86, using absolute relocations where necessary
for ELF to work.  
2) RIP addressing: Use SIB bytes for absolute relocations where RegBase=0, 
IndexReg=0.
3) The JIT can get the real address of cstpools and jmptables during
code emission, fix that for object code emission

489393d7b9 Add an option to allocate JITed global data separately from code. By
default, this option is not enabled to support clients who rely on
this behavior.

Fixes http://llvm.org/PR4483

A patch to allocate additional memory for globals after we run out is
forthcoming.
