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).

csmith check: pyramid: tolerate 1st row address
...
The first row of a pyramid can have a larger location delta than the
following, because there can be other things than a push between the
function entry point and the first push

Check_gen: patch for flat vs pyramid clang tables

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.
