invoke_xmethod & array_view
This replaces more pointer+length with gdb::array_view. This time,
around invoke_xmethod, and then propagating the fallout around, which
inevitably leaks to the overload resolution code.
There are several places in the code that want to grab a slice of an
array, by advancing the array pointer, and decreasing the length
pointer. This patch introduces a pair of new
gdb::array_view::slice(...) methods to make that convenient and clear.
Unit test included.
