flags.h: New variables align_loops...
* flags.h: New variables align_loops, align_loops_log,
align_jumps, align_jumps_log, align_labels, align_labels_log,
align_functions, align_functions_log.
* toplev.c: Define them.
(f_options): Handle -falign-* when they have no argument.
(main): Add logic to set variables for -falign-functions,
-falign-jumps, -falign-labels, -falign-loops.
Make it -fsched-verbose=<n> and -finline-limit=<n>.
(display_help): Change help to match options.
* final.c (LABEL_ALIGN): Default to align_labels_log.
(LABEL_ALIGN_MAX_SKIP): Default to align_labels-1.
(LOOP_ALIGN): Default to align_loops_log.
(LOOP_ALIGN_MAX_SKIP): Default to align_loops-1.
(LABEL_ALIGN_AFTER_BARRIER): Default to align_jumps_log.
(LABEL_ALIGN_AFTER_BARRIER_MAX_SKIP): Default to align_jumps-1.
* varasm.c (assemble_start_function): Handle align_functions.
* config/sparc/sparc.h: Don't declare sparc_align_*.
Don't provide LABEL_ALIGN_AFTER_BARRIER or LOOP_ALIGN.
(DEFAULT_SPARC_ALIGN_FUNCS): Delete; take functionality into
sparc.c.
(FUNCTION_BOUNDARY): Fix incorrect use---it's not just a request,
it's a promise.
* config/sparc/sparc.c: Delete sparc_align_loops,
sparc_align_jumps, sparc_align_funcs and the corresponding string
variables.
(sparc_override_options): Default align_functions on ultrasparc.
Delete -malign-* handling.
* config/mips/mips.c (override_options): On 64-bit targets,
try to align code to 64-bit boundaries.
(print_operand): New substitution, %~,
which aligns labels to align_labels_log.
* config/mips/mips.md (div_trap_normal): Use %~.
(div_trap_mips16): Likewise.
(abssi): Likewise.
(absdi2): Likewise.
(ffssi2): Likewise.
(ffsdi2): Likewise.
(ashldi3_internal): Likewise.
(ashrdi3_internal): Likewise.
(lshrdi3_internal): Likewise.
(casesi_internal): Likewise.
Plus corresponding documentation changes.
