This removes `BLS12_G1MUL` and `BLS12_G2MUL` precompiles because they are trivially replaceable by corresponding MSM precompiles. This reduces the number of precompile's addresses defined in this EIP from 9 to 7. The addresses of remaining 7 precompiles are changed to be continues. The Rationale entry describes why this change make sense. Additionally, the cost of MSM for single input (`k==1`) has been corrected to match the original MUL cost. The specification now suggests how this case should be implemented. Morever, because of the ABI compatibility between MUL and MSM all existing tests for MULs can be easily converted to tests for MSMs. The PoC of MUL and MSM precompiles equivalence is provided in [evmone PR#1042](ethereum/evmone#1042).
