Improve CALL tester

Detail:
  Tests/CALL,ffb:
  - Make compatible with (at least) RISC OS 3.1, for checking behaviour of old BASICs
  - Allow checking for stack usage
  - Mark fewer FPA registers as clobbered, to match the registers BASIC actually uses
  - Implement tests for the untested CALL routines
Admin:
  Tested against current BASIC/BASIC64 and BASIC/BASIC64 1.05


Version 1.64. Retagged as 'BASIC-1_64'
