James Henderson 5632da10d6 [CommandLine] Don't print empty sentinel values from EnumValN lists in help text ... In order to make an option value truly optional, both the ValueOptional attribute and an empty-named value are required. Prior to this change, this empty-named value appears in the command-line help text: -some-option - some help text =v1 - description 1 =v2 - description 2 = - This change improves the help text for these sort of options in a number of ways: 1) ValueOptional options with an empty-named value now print their help text twice: both without and then with '=<value>' after the name. The latter version then lists the allowed values after it. 2) Empty-named values with no help text in ValueOptional options are not listed in the permitted values. -some-option - some help text -some-option=<value> - some help text =v1 - description 1 =v2 - description 2 3) Otherwise empty-named options are printed as =<empty> rather than simply '='. 4) Option values without help text do not have the '-' separator printed. -some-option=<value> - some help text =v1 - description 1 =v2 =<empty> - description It also tweaks the llvm-symbolizer -functions help text to not print a trailing ':' as that looks bad combined with 1) above. This is mostly a reland of r353048 which in turn was a reland of r352750.
