Emits the merge immediate form of the IPF Deposit (dep) instruction, which is used for copying a number of bits specified by len with the value bit into a value value in a register at the bit position specified by pos.
// compile with: /EHsc
// processor: IPF
// Merge a "1" bit at bit 1 in 0x200
m = __m64_dep_mi(1, _m_from_int(0x200), 1, 1);
