The debugger relied on the environment stack. To fix it:
...
- absmi.c now tells who called the debugger, besides who it was calling
- this is used to control whether we allow a goal to be debugged.
- I have creep to start creeping immediately, and signal_creep to tell
the next meta-call to creep what it executes!
- The debugger uses CalledFromTheDebugger to know if it is within the
debugger. If so, we do not need to creep on leaving.

Include new instruction execute_cpred to perform tail optimisation for
...
builtins. Required changes:
- be careful about creeping in deallocate: it may be followed by
something that is not a cut nor a proceed.
- include new instruction in absmi.c: it is a merge of execute and
call_cpred.
- change compiler to generate execute even for C builtins.
- be careful with dexecute: it may not be done if execute_op is a C
builtin.
- if we are in execute_cpred, the garbage collector cannot trust P:
instead it must look at CP to find out the size of the current
environment. The macro gc_P receives that information.
- We don't need to change CP if we do a meta-call from within
execute_cpred (and we in fact cannot). Check places where we do
meta-calls: exec, clause in cdmgr, and lu_recorded.
