Sean Fertile a2f095f1a3 [PowerPC][MC] Support expressions in getMemRIX16Encoding.
Loosens an assert in getMemRIX16Encoding that restricts DQ-form instructions to

Hal Finkel 522e4d9d66 [PowerPC] Support asm parsing for bc[l][a][+-] mnemonics
PowerPC assembly code in the wild, so it seems, has things like this:

  bc+     12, 28, .L9

This is a bit odd because the '+' here becomes part of the BO field, and the BO
field is otherwise the first operand. Nevertheless, the ISA specification does
clearly say that the +- hint syntax applies to all conditional-branch mnemonics
(that test either CTR or a condition register, although not the forms which
check both), both basic and extended, so this is supposed to be valid.

This introduces some asm-parser-only definitions which take only the upper
three bits from the specified BO value, and the lower two bits are implied by
the +- suffix (via some associated aliases).

Fixes PR23646.

The mftb instruction was incorrectly marked as deprecated in the PPC
Backend. Instead, it should not be treated as deprecated, but rather be

year. Details can be found at:

This change will replace instances of the mftb instruction with the mfspr

behaviour.
