Michael J. Spencer c635710bcb [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.

Argyrios Kyrtzidis f385233881 Revert r166223 and the subsequent commits that depend on it, r166230 & r166235. 
This seems to have introduced assertion hit when building compiler-rt.

Daniel Dunbar f3cad36e59 Driver: Prep for tool chain specific argument translation. 
- Lift ArgList to a base class for InputArgList and DerivedArgList.
 
 - This is not a great decomposition, but it does embed the

   tool chains that don't want to do any translation.

 - No intended functionality change.

Eventually I hope to get rid of tool chain specific translation and
have each tool do the right thing, but for now this is the easiest way
to match gcc precisely (which is good for testing).
