2404a2f253 Added flag to skip very expensive part of the proof for prvInitialiseNewTask.
When the symbol `VERIFAST_SKIP_BITVECTOR_PROOF__STACK_ALIGNMENT` is defined in the preprocessor script, we skip the verification of the stack alignment. This part of the proof involves bit vector arithmetic and hence takes long to verify.
