John Stiles 9cef66fbf5 Fix use-after-free discovered by fuzzer. 
In cases where multiple variables were declared on a single line, it is
legal for variable initialization-expressions to reference variables
declared earlier in the var-decl statement. It is NOT legal for the
inliner to move those references up to the previous statement, where the
variable doesn't exist yet.

This is mitigated by disabling the IRGenerator inliner for var-decls
past the first one in a var-decls statement. (The optimizer will still
pass over this code later and is able to inline it correctly, if it is
worth doing.)
