Options: Use AliasArgs for -O -> -O2 translation. This way we can do the translation in the .td file rather than manually. llvm-svn: 187583

// Test that we parse and translate the -O option correctly.
// RUN: %clang -O -### %s 2>&1 | FileCheck -check-prefix=CHECK-O %s
Map -O to -O1 instead of -O2 rL82131 changed -O from -O1 to -O2, because -O1 was not different from -O2 at that time. GCC treats -O as -O1 and there is now work to make -O1 meaningful. We can change -O back to -O1 again. Reviewed By: echristo, dexonsmith, arphaman Differential Revision: https://reviews.llvm.org/D79916
