Sort pseudo instructions first while emitting enum's for target
instructions info. That puts them close to each other and to generic
G_* opcodes for GlobalISel. This makes it easier to build small jump
tables over opcodes that could be directly embedded into MatchTable's
Tablegen'erated for GlobalISel's InstructionSelect.

New order breaks `instregex`, thus this patch also fixes that.

There is an NFC going before this patch to tidy up the implementation a little and make the diff smaller.
