Josh Poimboeuf 0c671812f1 objtool: Move objtool_file struct off the stack 
Objtool uses over 512k of stack, thanks to the hash table embedded in
the objtool_file struct.  This causes an unnecessarily large stack
allocation and breaks users with low stack limits.

Move the struct off the stack.

Fixes: 042ba73fe7 ("objtool: Add several performance improvements")
