Johnny Chen 29a9103ee6 Add YIELD, WFE, WFI, and SEV instructions for disassembly only.
Plus add two formats: MiscFrm and ThumbMiscFrm.  Some of the for disassembly
only instructions are changed from Pseudo Format to MiscFrm Format.

Chris Lattner b06015aa69 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.

tMOVCCi pattern only valid for low registers, as the Thumb1 mov immediate to
register instruction only works with low registers. Allowing high registers
for the instruction resulted in the assembler choosing the wide (32-bit)
encoding for the mov, but LLVM though the instruction was only 16 bits wide,
so offset calculations for constant pools became incorrect, leading to
out of range constant pool entries.

Johnny Chen 9e60686a83 Add VCVTR (between floating-point and integer, VFP) for disassembly purpose.
The 'R' suffix means the to-integer operations use the rounding mode specified
by the FPSCR, encoded as Inst{7} = 0.

Chris Lattner 082f484074 make MachineModuleInfoMachO hold non-const MCSymbol*'s instead
of const ones.  non-const ones aren't very useful, because you can't
even, say, emit them.

Chris Lattner 996ec840d0 rejigger the world so that EmitInstruction prints the \n at
the end of the instruction instead of expecting the caller to
do it.  This currently causes the asm-verbose instruction 
comments to be on the next line.

Chris Lattner 41ad1905c9 sink handling of target-independent machine instrs (other
than DEBUG_VALUE :(  ) into the target indep AsmPrinter.cpp
file.   This allows elimination of the 
NO_ASM_WRITER_BOILERPLATE hack among other things.

Jim Grosbach d0a2f52f8f As of r79039, we still try to eliminate the frame pointer on leaf functions,
even when -disable-fp-elim is specified.

Chris Lattner b0d44c3807 refactor code so that LLVMTargetMachine creates the asmstreamer and
mccontext instead of having AsmPrinter do it.  This allows other 
types of MCStreamer's to be passed in.

Anton Korobeynikov 25df248382 Fix a gross typo: ARMv6+ may or may not support unaligned memory operations.
Even if they are suported by the core, they can be disabled
(this is just a configuration bit inside some register).

Allow unaligned memops on darwin and conservatively disallow them otherwise.

Johnny Chen 34a6afc68d Modified encoding bits specification for VFP instructions. In particular, the D
bit (Inst{22}) and the M bit (Inst{5}) should be left unspecified.  For binary
format instructions, Inst{6} and Inst{4} need to specified for proper decodings.

Chris Lattner 73de5fbfc3 Give AsmPrinter the most common expected implementation of
runOnMachineFunction, and switch PPC to use EmitFunctionBody.
The two ppc asmprinters now don't heave to define 
runOnMachineFunction.

Chris Lattner 94a946cac4 Remove the argument from EmitJumpTableInfo, because it doesn't need it.
Move the X86 implementation of function body emission up to 
AsmPrinter::EmitFunctionBody, which works by calling the virtual
EmitInstruction method.

constant pool emission.

Jeffrey Yasskin 091217be6f Kill ModuleProvider and ghost linkage by inverting the relationship between
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
GlobalValues now, and doesn't provide modules, it's renamed to
"GVMaterializer". Code that used to need a ModuleProvider to materialize
Functions can now materialize the Functions directly. Functions no longer use a
magic linkage to record that they're materializable; they simply ask the
GVMaterializer.

Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
the functions that refer to it. Instead, because Module now exposes the same
functionality ModuleProvider used to, we store a Module* in any
LLVMModuleProviderRef and translate in the wrapper methods.  The bindings to
other languages still use the ModuleProvider concept.  It would probably be
worth some time to update them to follow the C++ more closely, but I don't
intend to do it.

Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735.
