Attachment: Patch

Not that I particularly care, but I'm working on implementing a feature that will need JIT support, and I want to ensure it works correctly in non-JIT before touching the JIT portion at all.

Move these functions to header as "static inline bool", with "return false" in the non-ENABLE_METHODJIT_SPEW case

So I think the real problem, at its most basic, was defining JS_METHODJIT_SPEW if DEBUG.  Looking at configure.in, I think there's already logic to that effect anyway, so it seems pointless to have it.  Removed that, left the don't-#ifdef-so-much changes in place, with static-inlines for the relevant methods in the non-spew case.

This looks good. In order to preserve the existing logic that permits JS_METHODJIT_SPEW when !JS_METHODJIT but ENABLE_YARR_JIT, you'll also have to change configure.in:3270 to check $ENABLE_YARR_JIT in addition to $ENABLE_METHODJIT. I think that should be safe, but it wouldn't hurt to test various build configurations before landing.
