... and delete their second name.
compiler/options.m:
The internal names of many optimization options have traditionally
given no clue about which backend(s) they apply to, which made it
hard to document them. Change this by including either llds or mlds
in the names of these options, unless the rest of the name already
ruled out one or the other backend.
In one case, this exercise relevaled that an option that was classified
as MLDS-only is used by the LLDS backend as well. Reclassify this option.
Also, rename many options to the names they have in the opt_tuple.
Those names are more recent, and their naming is more consistent
(e.g. they are all verb phrases).
tools/make_optimization_options_db:
Delete the different-from-the-opt-tuple name alternatives.
tools/make_optimization_options_end:
Conform to the option renames.
Also, fix a bug. The list of options enabled at each optimization
level lists each option twice, once by its name in the opt_tuple
(which is what we use to actually implement optimization levels)
and once by its name in options.m (which we use to implement
the option that prints out the optimization levels). In one case,
the two names did not match; fix this.
compiler/optimization_options.m:
Rebuild this module with tools/make_optimization_options.

compiler/global_data.m:
compiler/handle_options.m:
compiler/ite_gen.m:

compiler/mercury_compile_mlds_back_end.m:
compiler/ml_optimize.m:
compiler/optimize.m:
compiler/options.m:
compiler/proc_gen.m:
compiler/stack_layout.m:
Conform to the option renames.
tests/warnings/help_opt_levels.err_exp:
Expect the fix to make_optimization_options_end.
tests/warnings/help_text.err_exp:
Expect the option reclassification.
