Check_gen: patch for flat vs pyramid clang tables
...
clang generates tables like this
LOC CFA rbx rbp r14 r15 ra
00000000000028a0 rsp+8 u u u u c-8
00000000000028a1 rsp+16 u u u u c-8
00000000000028a3 rsp+24 u u u u c-8
00000000000028a5 rsp+32 u u u u c-8
00000000000028a6 rsp+40 u u u u c-8
00000000000028aa rsp+64 c-40 c-16 c-32 c-24 c-8

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.

Fix next_instr_graph out-of-subroutine pointers
...
The disasm-based next_instr_graph would introduce next instructions out
of the current subroutine for eg. calls, jmp to plts, etc.

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.
