[PATCH] c++: fix string literal member initializer bug [PR90926]

build_aggr_conv did not correctly handle string literal member initializers. Extended can_convert_array to handle this case. The additional checks of compatibility of character types, and whether string literal will fit, would be quite complicated, so are deferred until the actual conversion takes

Go testsuite patch committed: Handle +builds line correctly in testsuite

This patch to the Go testsuite driver changes it to handle +build lines correctly, which is to say, in the same way that they are handled by the upstream test driver. Update several tests from the upstream repo to use "gc" and "!gccgo" as appropriate so that tests continue to pass. This cleans up
