Hal Finkel 5a49125fec Add a PPC inline asm constraint type for single CR bits
Now that the PowerPC backend can track individual CR bits as first-class
registers, we should also have a way of allocating them for inline asm
statements. Because these registers are only one bit, if an output variable is
implicitly cast to a larger integer size, we'll get an any_extend to that
larger type (this is part of the existing target-independent logic). As a
result, regardless of the size of the output type, only the first bit is
meaningful.

The constraint identifier "wc" has been chosen for this purpose. Although gcc
does not currently support allocating individual CR bits, this identifier
choice has been coordinated with the gcc PowerPC team, and will be marked as
reserved for this purpose in the gcc constraints.md file.
