Fix QtScript on 64-bit systems with gcc 8
Similar to commit 92836d052efb6d8073136e8507083f93fb60bb80 in
qtdeclarative, we must use memcpy to do a bit-wise conversion from the
JSCell *m_ptr to an intptr_t for JSValue tag operations.
This fixes the referenced task and all the failing auto-tests.
The most visible result was that
if ((jsvalue.immediateValue() & 0xffff000000000000ll) == 0xffff000000000000ll)
return static_cast<int32_t>(jsvalue.immediateValue());
was "optimized" to "return 0", breaking QScriptValue::toNumber() for
integer encoded values.
[ChangeLog][QtScript] Fix incorrect script evaluations on 64-bit systems
with gcc 8.
