Be less misleading when something goes wrong early.

In the recent icu4c breakage, we misinterpreted the "thrown during ...<clinit>"
to mean that <clinit> was the method that threw. This patch makes the wording
less easy to misinterpret.

The other thing that was confusing was the lack of a stack trace. It turns out
that dalvikvm tried to output a stack trace when the thread died, but it was
using LOGI. We'd have seen that on the device (which logs everything), but it
was filtered out by the host build's liblog. (Our ANDROID_LOG_TAGS was set to
"*:w".)
