d: Fix failing test with 32-bit compiler [PR114434]

Since the introduction of gdc.test/runnable/test23514.d, it's exposed an
incorrect compilation when adding a 64-bit constant to a link-time
address.  The current cast to size_t causes a loss of precision, which
can result in incorrect compilation.

	PR d/114434

gcc/d/ChangeLog:

	* expr.cc (ExprVisitor::visit (PtrExp *)): Get the offset as a
	dinteger_t rather than a size_t.
	(ExprVisitor::visit (SymOffExp *)): Likewise.
