Use gdb:array_view in call_function_by_hand & friends
This replaces a few uses of pointer+length with gdb::array_view, in
call_function_by_hand and related code.
Unfortunately, due to -Wnarrowing, there are places where we can't
brace-initialize an gdb::array_view without an ugly-ish cast. To
avoid the cast, this patch introduces a gdb::make_array_view function.
Unit tests included.
This patch in isolation may not look so interesting, due to
gdb::make_array_view uses, but I think it's still worth it. Some of
the gdb::make_array_view calls disappear down the series, and others
could be eliminated with more (non-trivial) gdb::array_view
detangling/conversion (e.g. code around eval_call). See this as a "we
have to start somewhere" patch.
