Add some Book-E instructions to the asm parser and printer.

[chmeee]

Summary

Adds the following instructions:

• mfpmr
• mtpmr
• icblc
• icblq
• icbtls

Fix the scheduling for mtspr on e5500, which uses CFX0, instead of
SFX0/SFX1 as on e500mc.

Not sure if it's best to have these in this file, or the ...e500.txt file.

(On Diff #85317)

As above, not sure if this belongs here or in ...e500.s tests. They're defined in the ISA, but only for the embedded profile (Book-III E). Since they're defined in Book-III, I put them here.

Only if they're specific to that processor line.

We discussed on IRC, but relaying here for posterity:

These instructions, and some others in this file, are part of the Book-III/E profile. A follow-on change to this will rename the -e500 files to -bookIIIe, and move these and the others into those files.
