Cherry pick of #744 for swift/main branch.

A prior change incorrectly treated the start of the `searchBounds` as
an always-valid word boundary, which resulted in a word boundary at
the start of a pattern unconditionally matching at the restart point
when finding all matches in a string.

This change corrects the usage to recognize word boundaries only at
the start of the `subjectBounds`.
