e837dead3c - Rename TargetInstrDesc, TargetOperandInfo to MCInstrDesc and MCOperandInfo and 
sink them into MC layer.
- Added MCInstrInfo, which captures the tablegen generated static data. Chang
TargetInstrInfo so it's based off MCInstrInfo.

016c5829a5 During bottom up fast-isel, instructions emitted to materalize registers are at top of basic block and do not have debug location. This may misguide debugger while entering the basic block and sometimes debugger provides semi useful view of current location to developer by picking up previous known location as current location. Assign a sensible location to the first instruction in a basic block, if it does not have one location derived from source file, so that debugger can provide meaningful user experience to developers in edge cases.

bea6f615ee Add support for alternative register names, useful for instructions whose operands are logically equivalent to existing registers, but happen to be printed specially. For example, an instruciton that prints d0[0] instead of s0.

f792fa90f1 Distinguish early clobber output operands from clobbered registers. 
Both become <earlyclobber> defs on the INLINEASM MachineInstr, but we
now use two different asm operand kinds.

The new Kind_Clobber is treated identically to the old
Kind_RegDefEarlyClobber for now, but x87 floating point stack inline
assembly does care about the difference.

This will pop a register off the stack:

  asm("fstp %st" : : "t"(x) : "st");

While this will pop the input and push an output:

  asm("fst %st" : "=&t"(r) : "t"(x));

We need to know if ST0 was a clobber or an output operand, and we can't
depend on <dead> flags for that.

ba8297ec08 Refactor MachO relocation generaration into the Target directories. 
Move the target-specific RecordRelocation logic out of the generic MC
MachObjectWriter and into the target-specific object writers. This allows
nuking quite a bit of target knowledge from the supposedly target-independent
bits in lib/MC.

a347f85dbe Starting to refactor Target to separate out code that's needed to fully describe 
target machine from those that are only needed by codegen. The goal is to
sink the essential target description into MC layer so we can start building
MC based tools without needing to link in the entire codegen.

First step is to refactor TargetRegisterInfo. This patch added a base class
MCRegisterInfo which TargetRegisterInfo is derived from. Changed TableGen to
separate register description from the rest of the stuff.

4e5885dc0f Don't include config.h in public headers 
Replace it with llvm-config.h, which defines a subset of
config.h's macros "so that they can be in exported headers 
and won't override package specific directives", e.g.,
PACKAGE_NAME.

Endian.h wasn't using any macros at all though, so just delete
the include there instead.
