Previously for instructions like fxsave we would print "opaque ptr" as part of the memory operand. Now we print nothing.
We also no longer accept "opaque ptr" in the parser. We still accept any size to be specified for these instructions, but we may want to consider only parsing when no explicit size is specified. This what gas does.

aliases based on 16/32-bit mode to choose the default.
This allows the instruction selection to follow mode in Intel syntax. And allows a suffix to be used to change size.
This matches gas behavior from what I could tell.

LEA variants in Intel syntax. The memory operand is inherently unsized.

memory offset instructions.
-Assembly parser now properly check the size of the memory operation specified in intel syntax. So 'mov word ptr [5], al' is no longer accepted.
-x86-32 disassembly of these instructions no longer sign extends the 32-bit address immediate based on size.
-Intel syntax printing prints the ptr size and places brackets around the address immediate.
Known remaining issues with these instructions:
-Segment override prefix is not supported. PR16962 and PR16961.
-Immediate size should be changed by address size prefix.
