Fix QtScript crash on 64bit with JIT.v5.0.1
During back-trace generation we calculate a code offset towards JIT generated
code. Using JITCode::offsetOf() will crash/assert if the offset doesn't fit
into 32 bits, because the generated code can only encode relative offsets
in 32-bits and not 64-bits. However in this context - backtrace generation -
we just want to calculate the offset and are not interested in this
architectural limitation, therefore we can just calculate the offset ourselves
using the fully sized uintptr_t.
