Quick backend: rename target-specific #defines

Another step towards a single compiler.  The #include build mechanism
relies on macros with the same name to take on different values for
our various targets.  This CL prepends a target-specific string
(and exposes some needed by common code as functions rather than #defines).

Macros and #defines still available for use from target-dependent code,
but functions added for target independent use.  For example,
rRET0 for Arm becomes rARM_RET0 in target-dependent code, and
targetRegister(kRet0) in target-independent code.

No logic changes, other than adding functions to return previously #defined
values.  As of this CL, the primary target includes, xxxLIR.h, have no
macro collisions.
