* vm_insnhelper.c (vm_getivar): specify inline instead of static inline.
vm_getivar is called by vm_call_ivar and vm_getinstancevariable.
At least with GCC 4.8 and 5.3 on Linux, they are inlining it into
vm_call_ivar but not vm_getinstancevariable.
By `inline`, they correctly inline it and gains performance.
Speedup ratio: compare with the result of `ruby 2.4.0dev (2016-04-23
trunk 54727) [x86_64-linux]' (greater is better)
name built-ruby
loop_whileloop 1.001
vm1_ivar* 1.189
vm1_ivar_set* 1.024
Note tha `inline`'s meaning is different between old GCC
and C99. Old GCC's inline means C99's extern inline.

Since Ruby specify -std=iso9899:1999, it works like C99.
