arm.h (BIGGEST_FIELD_ALIGNMENT): Define instead of ADJUST_FIELD_ALIGN if IN_TARGET_LIBS.

* config/arm/arm.h (BIGGEST_FIELD_ALIGNMENT): Define instead of
ADJUST_FIELD_ALIGN if IN_TARGET_LIBS.
Replace occurances of '???' with 'XXX' incase they are mistaken for trigraphs.
(THUMB_PRINT_OPERAND_ADDRESS): abort if a compound address does not have a
register for the first operand.
