A few low-level gas optimizations.

Changes to contracts/utils/Bytecode.sol:

  • creationCodeFor has been changed to use PUSH2 instead of PUSH4 since there is a max contract size limit of 24576 bytes which is less than 2^16 = 65536 (uint16). Also PUSH1 0 instructions have been changed to RETURNDATASIZE.
  • codeAt has been changed so that only one subtraction is used to calculate size and also an extra addition in the assembly block has been removed to replace 0x20 + 0x1f with 0x3f.

All tests are passing.
