(label_to_alignment): Only use LABEL_TO_ALIGNMENT if CODE_LABEL_NUMBER <= max_labelno. * output.h (label_to_max_skip): New prototype. * config/i386/i386.c (ix86_avoid_jump_misspredicts): Renamed to... (ix86_avoid_jump_mispredicts): ... this. Don't define if ASM_OUTPUT_MAX_SKIP_ALIGN isn't defined. Update comment. Handle CODE_LABELs with >= 16 byte alignment or with max_skip == (1 << align) - 1. (ix86_reorg): Don't call ix86_avoid_jump_mispredicts if ASM_OUTPUT_MAX_SKIP_ALIGN isn't defined.
