[X86] Update RET/LRET instruction to use the same naming convention as IRET (PR36876). NFC
Be more consistent in the naming convention for the various RET instructions to specify in terms of bitwidth.
Helps prevent future scheduler model mismatches like those that were only addressed in D44687.

[X86] Support LEA64_32r in processInstrForSlow3OpLEA and use INC/DEC when possible.
Move the erasing and iterator updating inside to match the
other slow LEA function.
I've adapted code from optTwoAddrLEA and basically rebuilt the
implementation here. We do lose the kill flags now just like
optTwoAddrLEA. This runs late enough in the pipeline that
shouldn't really be a problem.

[X86FixupLEAs] Turn optIncDec into a generic two address LEA optimizer. Support LEA64_32r properly.
INC/DEC is really a special case of a more generic issue. We should also turn leas into add reg/reg or add reg/imm regardless of the slow lea flags.
This also supports LEA64_32 which has 64 bit input registers and 32 bit output registers. So we need to convert the 64 bit inputs to their 32 bit equivalents to check if they are equal to base reg.
One thing to note, the original code preserved the kill flags by adding operands to the new instruction instead of using addReg. But I think tied operands aren't supposed to have the kill flag set. I dropped the kill flags, but I could probably try to preserve it in the add reg/reg case if we think its important. Not sure which operand its supposed to go on for the LEA64_32r instruction due to the super reg implicit uses. Though I'm also not sure those are needed since they were probably just created by an INSERT_SUBREG from a 32-bit input.

[X86] Merge the different Jcc instructions for each condition code into single instructions that store the condition code as an operand.
Summary:
This avoids needing an isel pattern for each condition code. And it removes translation switches for converting between Jcc instructions and condition codes.
Now the printer, encoder and disassembler take care of converting the immediate. We use InstAliases to handle the assembly matching. But we print using the asm string in the instruction definition. The instruction itself is marked IsCodeGenOnly=1 to hide it from the assembly parser.

Followup on Proposal to move MIR physical register namespace to '$' sigil.
Discussed here:
http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html
In preparation for adding support for named vregs we are changing the sigil for
physical registers in MIR to '$' from '%'. This will prevent name clashes of
named physical register with named vregs.
