lang/gprolog: recover GNU Prolog under FreeBSD.

Update to version 1.4.5 released in 2020.
Make it build and run with Clang 10:

- clang has no register reservation for x86, hence patch-EnginePl_machine.h
  and -DNO_MACHINE_REG_FOR_REG_BANK to prevent using missing feature;
- add patch-Ma2Asm_x86__64__any.c fetched from upstream SourceForge
  post-release commit dealing with PIC issues;
- disable usage of spinlocks that results in a hang eating all available
  CPU cycles; fixed with -DUSE_LOCKS=1 -DUSE_RECURSIVE_LOCKS=1
  -DUSE_SPIN_LOCKS=0;
- the software uses bundled dlmalloc dated back 2011 that replaces
  functions like calloc() with own implemenations and it's calloc()
  sometimes fails to clear allocated memory; this results in SIGSEGV
  when its own hash-table implementation dereferences junk that
  supposed to be NULL pointer, so it fails to complete build;
  fixed with MMAP_CLEARS=0.

+GNU Prolog is a free Prolog compiler with constraint solving over finite
+domains developed by Daniel Diaz.
+
+GNU Prolog accepts Prolog+constraint programs and produces native binaries
+(like gcc does from a C source). The obtained executable is then stand-alone.
+The size of this executable can be quite small since GNU Prolog can avoid to
+link the code of most unused built-in predicates. The performances of GNU
+Prolog are very encouraging (comparable to commercial systems).
+
+Beside the native-code compilation, GNU Prolog offers a classical interactive
+interpreter (top-level) with a debugger.
+
+The Prolog part conforms to the ISO standard for Prolog with many extensions
+very useful in practice (global variables, OS interface, sockets,...).
+
+GNU Prolog also includes an efficient constraint solver over Finite Domains
+(FD). This opens contraint logic pogramming to the user combining the power
+of constraint programming to the declarativity of logic programming.
