Remove code for setting the VEX L-bit as a function of operand size from the code emitters and the disassembler table builder. Fix a couple instructions that were still missing VEX_L.

This is a generally useful utility; there's no reason to have it hidden
in CodeGenDAGPatterns.cpp.

Also, rename it to fit the other comparators in Record.h

Make custom operand parsing mnemonic indices use the same mnemonic table as the match table. Reorder fields in OperandMatchEntry to provide the least amount of padding for in tree targets.

llvm-svn: 164109

Use variable type for index into mnemonic table. Shrinks size of index field on in tree targets. Saving static data space.

Now where we used to call ReInitMCSubtargetInfo, we actually recompute
the same information as InitMCSubtargetInfo instead of only setting
the feature bits.

Map the CodeGenSchedule object model onto data tables. The structure
of the data tables is defined in MC, so for convenience we include
MCSchedule.h. The alternative is maintaining a redundant copy of the
table structure definitions. Mapping the object model onto data tables
is sufficiently complicated that it should not be interleaved with
emitting source code. This avoids major problem with the backend for
itinerary generation.

Keep GCC's warnings happy. It can't reason out that the state machine won't
ever hit the potentially uninitialized use in OPC_FilterValue.

Revert r163878 as it breaks on targets with alternate register names. Such targets do not exist in the main tree so this was not noticed.

Allow the second opcode info table to be 8, 16, or 32-bits as needed to represent additional fragments. This recovers some space on ATT X86 syntax and PowerPC which only need 40-bits instead of 48-bits. This also increases ARM to 64-bits to fully encode all of its operands.

llvm-svn: 163880

Reduce size of register name index tables by using uint16_t for all in tree targets. If more than 16-bits are needed for any out of tree targets, code will detect and use uint32_t instead.

Fix an issue in r163814.

48-bit if necessary, in order to reduce the generated code size.

We have 900 cases not covered by OpcodeInfo in ATT AsmWriter and more in Intel
AsmWriter and ARM AsmWriter.

This patch reduced the clang Release build size by 50k, running on a Mac Pro.
