  Log Message:
  -----------
  Inline basic_string::erase for fastpath where __n == npos

Summary:
This change checks for the case where people want to erase a string to the end, i.e., __n == npos, and inlines the call if so.

This also demonstrates keeping the ABI intact for V1, but inlining the erase() method for unstable.
