b9762c07cb Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static 
ID member as the sole unique type identifier.  Clean up APIs related to this change.

e2833a21c2 Rename DBG_LABEL PROLOG_LABEL, because it's only used during prolog emission and 
thus is a much more meaningful name.

5e3c60fb63 Add instruction encoding for the Neon VMOV immediate instruction. This changes 
the machine instruction representation of the immediate value to be encoded
into an integer with similar fields as the actual VMOV instruction.  This makes
things easier for the disassembler, since it can just stuff the bits into the
immediate operand, but harder for the asm printer since it has to decode the
value to be printed.  Testcase for the encoding will follow later when MC has
more support for ARM.

5fef80c5aa change the LabelSDNode to be EHLabelSDNode and make it hold 
an MCSymbol.  Make the EH_LABEL MachineInstr hold its label
with an MCSymbol instead of ID.  Fix a bug in MMI.cpp which
would return labels named "Label4" instead of "label4".

149cf816bb 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.

7acf9be6c4 move target-independent opcodes out of TargetInstrInfo 
into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

b5ec39e2dc Remove ISD::DEBUG_LOC and ISD::DBG_LABEL, which are no longer used. 
Note that "hasDotLocAndDotFile"-style debug info was already broken;
people wanting this functionality should implement it in the
AsmPrinter/DwarfWriter code.

502d93267d Make the need-stub variables accurate and consistent. In the case of 
MachineRelocations, "stub" always refers to a far-call stub or a
load-a-faraway-global stub, so this patch adds "Far" to the term. (Other stubs
are used for lazy compilation and dlsym address replacement.) The variable was
also inconsistent between the positive and negative sense, and the positive
sense ("NeedStub") was more demanding than is accurate (since a nearby-enough
function can be called directly even if the platform often requires a stub).
Since the negative sense causes double-negatives, I switched to
"MayNeedFarStub" globally.

a3cf123e86 strength reduce a ton of type equality tests to check the typeid (Through 
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

31fcbdefbb Introduce the TargetInstrInfo::KILL machine instruction and get rid of the 
unused DECLARE instruction.

KILL is not yet used anywhere, it will replace TargetInstrInfo::IMPLICIT_DEF
in the places where IMPLICIT_DEF is just used to alter liveness of physical
registers.
