Matthew Flatt b7b273895a fix bytecode optimizer bugs ... Certain unsafe operations were allowed to propagate across a `lambda' boundary (where space safety is known not to be an issue), which could lead to duplicate uses of a "once used" variable if the relevant `lambda' is inlined. Furthermore, `lambda' boundary crossing wasn't detected in the case that the operation to propagate was propagated through an intermediate variable without a `lambda' crossing. Merge to 5.2.1 (cherry picked from commit 7850a26dfe)		2012-01-11 16:09:22 -07:00
