clover: Add support for CL_MAP_WRITE_INVALIDATE_REGION

OpenCL 1.2 CL_MAP_WRITE_INVALIDATE_REGION sounds a lot like
PIPE_TRANSFER_DISCARD_RANGE:

From OpenCL 1.2 spec:
    The contents of the region being mapped are to be discarded.

From p_defines.h:
    Discards the memory within the mapped region.

v2: Move the code for validating flags to the front-end as
    suggested by Francisco Jerez
