Don't lie to the c++ about some pointer alignment 

Second try cleaning up cast-alignment problems surrounding need_result_buf().
Clang gave a bunch of warnings like
vvp/vpi_const.cc:196:34: warning: cast from 'char *' to 'p_vpi_vecval' (aka 't_vpi_vecval *') increases required alignment from 1 to 4 [-Wcast-align]

This version is verbose and changes the prototype for need_result_buf().
But it is semantically (c++) correct, and makes need_result_buf() feel like malloc().
