Message:

Added some more dataLog info for OSR exits.
<​https://webkit.org/b/131120>

Reviewed by Michael Saboff.

Adding info about the OSR exit index, the bytecode index of the bytecode
that is OSR exiting, and the reason for the OSR exit. This change is
for debugging code which only comes into play when we use the
--printEachOSRExit option.
