-finline means "pay attention to the inline keyword", ie consider 
functions marked DECL_INLINE for inlining. Java has no "inline" keyword, 
so all functions (or at least the local, non-virtual ones) are inline 
candidates. flag_inline_functions is the correct flag to set to get the 
inliner to do its stuff.

I guess we could make both flags work, but I don't really want to 
encourage use of the broken inliner, just make it available for the few 
cases where it helps. This is just a stop-gap until we get tree-level 
inlining for Java.
