Create a new function that returns a register descriptor given its
ID. Change ipa_reg_offset() and ipa_reg_n_offset() so they take a
register descriptor argument rather than an IPA pointer and register
ID. Have them accept null pointers (and return an invalid 0 offset),
to avoid the need for excessive error checking. (A warning is issued
whenever ipa_reg() returns 0).
Call ipa_reg() or ipa_reg_n() to look up information about the
register before calls to ipa_reg_offset() and ipa_reg_n_offset().
Delay looking up offsets until they're needed to read or write
registers.
