Rename the fallthrough attribute to better align with the kernel
version. Copy the definition from include/linux/compiler_attributes.h
including the #else clause. Adding the #else clause allows the tools
compiler.h header to drop the check for a definition entirely and keeps
both definitions together.
Change any __fallthrough statements to fallthrough anywhere it was used
within perf.
This allows other tools to use the same key word as the kernel.
Committer notes:
Did some missing conversions to:
builtin-list.c
Also included gtk.h before the 'fallthrough' definition in:
tools/perf/ui/gtk/hists.c
tools/perf/ui/gtk/helpline.c
tools/perf/ui/gtk/browser.c
As it is the arg name for a macro in glib.h:
/var/home/acme/git/perf-tools-next/tools/include/linux/compiler-gcc.h:16:55: error: missing binary operator before token "("
16 | # define fallthrough __attribute__((__fallthrough__))
| ^
/usr/include/glib-2.0/glib/gmacros.h:637:28: note: in expansion of macro ‘fallthrough’
637 | #if g_macro__has_attribute(fallthrough)
