gcc-common.h: Update for GCC 10
[ Upstream commit c7527373fe28f97d8a196ab562db5589be0d34b9 ]
Remove "params.h" include, which has been dropped in GCC 10.
Remove is_a_helper() macro, which is now defined in gimple.h, as seen
when running './scripts/gcc-plugin.sh g++ g++ gcc':
In file included from <stdin>:1:

Add -Wno-format-diag to scripts/gcc-plugins/Makefile to avoid
meaningless warnings from error() formats used by plugins:

scripts/gcc-plugins/structleak_plugin.c:253:12: warning: unquoted sequence of 2 consecutive punctuation characters ‘'-’ in format [-Wformat-diag]
