stupid simple EVM assembler

masm.h

// For example take this code
//    XPUSH(1,1) ff
//    XPUSH(1,1) ee
//    XAND(1,1)
// run it through the preprocessor and tr
//    gcc -E -P -x c-header -include masm.h test.evm | tr -d [:space:]
// and get this output
//    e011ffe011eed611
// Haven't figured out labels yet, might have to just count.
// No, this is not suitable for real work, but will suffice
// for initial testing, and was easy to write.
