HandlePrefixedOrGroupedOption - The specified argument string (which started with at least one '-') does not fully match an available option.
Check to see if this is a prefix or grouped option. If so, split arg into output an Arg/Value pair and return the Option to parse it with.

This function parses the given arguments using the LLVM command line parser.
Note that the only stable thing about this function is its signature; you cannot rely on any particular set of command line arguments being interpreted the same way across LLVM versions.

LookupNearestOption - Lookup the closest match to the option specified by the specified option on the command line.
If there is a value specified (after an equal sign) return that as well. This assumes that leading dashes have already been stripped.

Backslashes are interpreted in a rather complicated way in the Windows-style command line, because backslashes are used both to separate path and to escape double quote.
This method consumes runs of backslashes as well as the following double quote if it's escaped.

The later is accepted for arguments that don't allow a value (-foo) the former is rejected (-foo=).
