Option aliases in option groups were previously disallowed by an assert.
As far as I can tell, there was no technical reason for this, and I would
like to be able to put cl.exe compatible options in their own group for Clang,
so let's change the assert.
llvm-svn: 186838
Summary:
This allows the clang driver to put MSVC compatible options in the same
enumerator space as its normal options but exclude them from normal
option parsing.
Also changes the standard ParseArgs() method to consider unknown
arguments with a leading slash as being inputs rather than flags.

No functionality change.
This is preparing to move response file parsing into lib/Option so it
can be shared between clang and lld. This change isn't just a
micro-optimization. Clang's driver uses a std::set<std::string> to
unique arguments while parsing response files, so this matches that.

Option groups don't have prefixes. Option dumping is basically dead
code unless there is something wrong with the option table, so this
isn't an important crasher.

This is in preparation for switching the clang driver over to using LLVM's
Option library. Richard Smith introduced most of these changes to the clang
driver in r167638.

Most of these are updating the new R600 target and fixing up a few
regressions that have creeped in since the last time I sorted the
includes.
