0fa595f073 Fix PR7174, a couple o Mips fixes: 
- Fix a typo for PIC check during jmp table lowering
- Also fix the "first jump table basic block is not
considered only reachable by fall through" problem, use this
ad-hoc solution until I come up with something better.

9ae74337ef sink the arm implementations of ASmPrinter and MCInstLower 
out of the AsmPrinter directory into libarm.  Now the
ARM InstPrinters depend jsut on the MC stuff, not on vmcore
or codegen.

4d232b674d fix a layering problem by moving the x86 implementation 
of AsmPrinter and InstLowering into libx86 and out of the
asmprinter subdirectory.  Now X86/AsmPrinter just depends on
MC stuff, not all of codegen and LLVM IR.

b2ad0066f5 ARM has to provide its own TargetLowering::findRepresentativeClass because its scalar floating point registers alias its vector registers.

1dd74c37c5 X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same 
instruction, we only want to allow the one for the current subtarget.
 - This also fixes suffix matching for jmp instructions, because it eliminates
   the ambiguity between 'jmpl' and 'jmpq'.

dc21ac2e0a Since ARM emits inline jump tables as part of the ConstantIsland pass, 
it should set the jump table encloding the EK_Inline. This prevents
a second, unused, copy of the table from being emitted after the function
body. PR6581.

f58b5d7ad0 TblGen/AsmMatcher: Add support for honoring instruction Requires<[]> attributes as part of the matcher. 
- Currently includes a hack to limit ourselves to "In32BitMode" and "In64BitMode", because we don't have the other infrastructure to properly deal with setting SSE, etc. features on X86.

150021561c Target: Give the TargetAsmParser access to the TargetMachine. 
- Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this.

033201e862 Make more explicit and add some currently disabled error messages for 
stack realignment on ARM.

Also check for function attributes as we do on X86 as well as
make explicit that we're checking can as well as needs in this function.

and a combine pattern to use it for setting a bit-field to a constant
value. More to come for non-constant stores.
