4d53e7798c Don't reserve R2 on Darwin/PPC 
Now that only the register-scavenger version of the CR spilling code remains,
we no longer need the Darwin R2 hack. Darwin can use R0 as a spare register in
any case where the System V ABI uses it (R0 is special architecturally, and so
is reserved under all common ABIs).

A few test cases needed to be updated to reflect the register-allocation changes.

c5ddb74089 These tests no longer require linear scan because reserved register coalescing is now universal.
