Committed to branch dmalcolm/jit:
I tracked down the crash in dwarf2out.c mentioned in the commit message
for 6e624036e3f47c6ca4ae2e99974b74aa29f11eca:
"base_types" wasn't being flushed between invocations, leading to it
containing garbage that might be collected (it's not GTY-labelled), and
duplicate copies of types that appeared to violate reference-counting
checking in the DWARF string pruner, due to multiple copies of the
string "__unknown__".
Release it.
With this commit, *almost* all of the test suite runs successfully at
optimization level 3, the exception being a crash in test-linked-list.c
that I've yet to figure out.
