Ensure that array types with complicated length expressions are
handled correctly by lowering expression types in the lowering pass.
This required some adjustment of constant expression types to not
report too many errors for circular constant expressions. We now
record error types in the Named_constant type. If we find the
circularity due to lowering the Named_constant, we use that location
for the error message; this retains the error location we used to use.

I forgot to update the name of the map[string]bool type descriptor
used in go-fieldtrack.c. This didn't cause any errors because it's a
weak symbol, and the current testsuite has no field tracking tests.

On ppc64 gotest treats data variables whose names begin with "Test" as
tests to run. This is to support the function descriptors used for
ppc64 ELF ABI v1. This causes gotest to think that TestAddr6 is a
test, when it is actually a variable. For a simple fix until we can
figure out how to write gotest properly, rename the variable.

As part of the change to larger character lengths, the string copy
algorithm was temporarily pessimized to get around some spurious
-Wstringop-overflow warnings. Having tried a number of variations of
this algorithm I have managed to get it down to one spurious warning,
only with -O1 optimization, in the testsuite. This patch reinstates
the optimized variant and modifies this one testcase to ignore the
warning.
Regtested on x86_64-pc-linux-gnu.
