Ayman Musa 62d1c71676 [X86] Added missing mayLoad/mayStore attributes to some X86 instructions.
Throughout the effort of automatically generating the X86 memory folding tables these missing information were encountered.
This is a preparation work for a future patch including the automation of these tables.

Craig Topper 955308fbee [X86] Remove many operands that represent memory stores from outs to ins. These operands are the registers and immediates that specify the memory address not the memory itself thus they are inputs.

Craig Topper 5ccb61781f Add an x86 prefix encoding for instructions that would decode to a different instruction with 0xf2/f3/66 were in front of them, but don't themselves have a prefix. For now this doesn't change any bbehavior, but plan to use it to fix some bugs in the disassembler.

Craig Topper ae11aed9d7 Separate the concept of 16-bit/32-bit operand size controlled by 0x66 prefix and the current mode from the concept of SSE instructions using 0x66 prefix as part of their encoding without being affected by the mode.
This should allow SSE instructions to be encoded correctly in 16-bit mode which r198586 probably broke.

Eric Christopher c0a5aaeab0 [x86] Rename In32BitMode predicate to Not64BitMode
That's what it actually means, and with 16-bit support it's going to be
a little more relevant since in a few corner cases we may actually want
to distinguish between 16-bit and 32-bit mode (for example the bare 'push'
aliases to pushw/pushl etc.)
