0aef57e37f fix a 6g crash after type errors.
do not bother warning about marks left
on stack after syntax errors.

leave OCONV nodes in tree to avoid type errors
arising from multiple walks.

e81d97ea84 clean up gmove:
* conversions all in one place.
	* no separate load, store phases;
	  direct memory addressing when possible
	  (this is the x86 after all!).
	  avoids extra registers, extra MOVQs.
	* fixes int32 -> uint64 bug
	  (was zero-extending)
