[rfa] Do not expect frame base for inlined functions

[rfa] Do not expect frame base for inlined functions

[Daniel Jacobowitz]

I'm pretty sure this is correct.  Inlined subroutine DIEs should
generally not have a DW_AT_frame_base (the inlined instance does not
have a frame).  But it's fine for them to have variables which use
DW_OP_fbreg, and they'll use the enclosing DW_TAG_subprogram's frame
base.  OK to commit?

(Tested x86_64-linux, no regressions)
