st/glsl_to_tgsi: use correct writemask when converting generic intrinsics

This fixes a bug when lowering ballotARB: previously, using writemask 0xf,
emit_asm would create TGSI_OPCODE_BALLOT instructions that span two registers
to cover 4 64-bit channels. This could trample over other a neighbouring
temporary.
