[Options] Add prefixes to options.
Each option has a set of prefixes. When matching an argument such as -funroll-loops. First the leading - is removed as it is a prefix. Then a lower_bound search for "funroll-loops" is done against the option table by option name. From there each option prefix + option name combination is tested against the argument. This allows us to support Microsoft style options where both / and - are valid prefixes. It also simplifies the cases we already have where options come in both - and -- forms. Almost every option for gnu-ld happens to have this form. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166444 91177308-0d34-0410-b5e6-96231b3b80d8
