Some of the aeabi functions were missing PACBTI support. The lack of it resulted in exceptions at runtime if the running environment had PAC and/or BTI enabled. This patch adds this support. This involves the addition of PACBTI instructions, depending on whether each of these features is enabled, plus the saving and restoring of the PAC code that resides in r12. Some of the common code has been put in preprocessor macros to reduce duplication, but not all, especially since some register saving and restoring is very specific to each context.
