Migrate from ttmath to stint (#24) 
* Constants and accounts compile as standalone

* Mass replace ttmath by Stint

* Adapt utils_numeric proc

* Adapt memory.nim

* Deactivate "ValidationError" test that requires pow(2, 256) function

* Fix state_db toByteArrayBE

* Fix more getUint toInt conversion

* Remove absolute value ambiguous call

* Stub-ify proc and opcode that requires pow - https://github.com/status-im/nim-stint/issues/37

Alexander Ivanov 99921f38cb Pass more tests, use UInt256 more often 
82 / 189 arithmetic
55 / 62 logic
77 / 78 stack

Most errors are the same sstore gascost bug, also next work on flow and memory
