escape: Analyze function values and conversions.

The analysis for variables defined as function literals did not
properly analyze the underlying function literal when it was converted
to a function type.  Also, when analyzing composite literals with
function literals as arguments, the connection between the composite
literal and the function literal was ignored.

* varasm.c (handle_cache_entry): Fix logic.

compiler: Mark non-escaping variables that aren't addressed.

When optimizing allocations, only variables that had their address
taken somewhere in the program were marked as non-escaping.
There are several cases where non-addressed variables might cause
extra allocations.
