Store OptTable::Info::Name as a StringRef
This is a recommit of 8ae18303f97d5dcfaecc90b4d87effb2011ed82e,
with a few cleanups.
This avoids implicit conversion to StringRef at several points, which in
turns avoid redundant calls to strlen.
As a side effect, this greatly simplifies the implementation of
StrCmpOptionNameIgnoreCase.
It also eventually gives a consistent, humble speedup in compilation
time (timing updated since original commit).
