Add --print-internal-representation to goto-instrument
...
This flag pretty-prints every instruction in the entire program. I use
it to learn about CPROVER's internal representation of particular
constructs, by passing in --print-internal-representation on a one-line
C program.

Avoid repeated computation of guardt::operator-=
...
Each iteration of the loop yields the same expression. Avoiding repeated
construction enables trivial sharing rather than relying on merge_irepst for
a reduced memory footprint, and reduces the computational cost as
guardt::operator-= is non-trivial.

Rework and fix parsing of unicode strings
...
We cannot arbitrarily convert strings to unicode representation as this would
affect their size. Instead, only the unicode portion of a non-wide string must
be encoded. As part of this work the code duplication
unescape_string/unescape_wide_string is resolved. A new regression test confirms
that the previous implementation was broken (and is now fixed).

Support return statements in C(!) constructors/destructors
...
constructors/destructors are a GCC extension, and their return type must be
void as checked earlier. As the type is then replaced by
ID_constructor/ID_destructor, and checks on the return type must consider this
case.
