Nikita Popov a939805641 Use serialize_precision for var_dump() 
var_dump() is debugging functionality, so it should print
floating-point numbers accurately. We do this by switching
to serialize_precision, which (by default) will print with
as much precision as necessary to preserve the exact value
of the float.

This also affects debug_zval_dump().

Closes GH-5172.
