[SYCL] Fix StringLiteral Ctor issue from #3504.

Erich Keane · Erich Keane · commit c961d3ed1233 · 2021-04-09T06:11:30.000-07:00
I'm not sure what causes this to not like this conversion, the error
message seems incorrect and only on certain configs of the build, but we
should fix the build anyway.  This calls the StringRef pointer-size
directly, rather than having the StringLiteral type do it.
