New Revision: 293417

URL: http://llvm.org/viewvc/llvm-project?rev=293417&view=rev
Log:
Add some Book-E instructions to the asm parser and printer.

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.

Addresses PR 31538.
