Improve inlining when compiling with -Og
* src/conf_post.h (EXTERN_INLINE) [!EMACS_EXTERN_INLINE]:
Make it static inline, not merely static. This is a worthwhile
performance improvement on my two platforms A and B (see below).
On my platform A this change improves user+system CPU performance of
‘make compile-always’ by 52% on an -Og build, and by 1.4% on the
default -O2 build. On my platform B this improves the same benchmark
by 41% on an -Og build, and by -0.8% on the default -O2 build.
That "-0.8%" is a small negative for this change, and I recall that
it is why I didn't make this change earlier. However, Platform B uses
an older GCC so we needn't worry overmuch about this small negative.
With this change the performance advantage of -O2 over -Og has dropped
on platform A; formerly -O2 was 87% faster than -Og, and now it is
only 25% faster. On platform B the performance advantage of -O2 over
-Og has dropped from being 62% faster to being 14% faster.

The point may be changed by the time perform-replace is called, e.g.,
