[JSC] ExpressionInfo::Encoder::adjustInstPC should take an index instead of a
pointer
https://bugs.webkit.org/show_bug.cgi?id=309843
rdar://172411808
Reviewed by Mark Lam.
adjustInstPC() previously took a raw EncodedInfo* pointer that aliased
m_expressionInfoEncodedInfo's backing buffer. This is fragile since the
pointer can become invalid if the vector is resized.
Change adjustInstPC() to take an unsigned index instead. An integer
index remains valid across reallocations since vector element access
always recomputes the address from the current base pointer.
