synth: tolerate rbp def/undef merges (one way only)
...
The easy way of RBP defined vs. undefined merge is implemented (if a
block is defined with RBP undef, we tolerate merging upon it with a
defined RBP by losing this information).

Fix rbp pop heuristic
...
Add criterion to rbp pop detection:
iii) that are the last references to %rbp in a `Def` in the
subroutine's CFG (cf (ii)).

Ignore ghost subroutines for clang
...
A ghost subroutine is a subroutine having, in the IR representation, no
content. At clang -O0, some might be generated, eg.
<foo_func>:
foo_addr nop
which translates to Empty in BIL.

Add flag to never go back to undefined rbp
...
Once rbp has been set in the DWARF, if this flag is set, nothing will
remove it from the table. This mimicks gcc and allows us to check easily
our tables against theirs.
