Two adjustments in the inline code over how we locate a loop in an inline sequence.

inline sequence.

1. If we don't find a loop from the proc name, then use the last
inlined alien before the guard alien.

2. Relax the test for proc name equality to ignore whitespace and a
trailing ().  Sometimes binutils names a procedure as 'foo()' but
symtab calls it 'foo' and we want these names to match.
