* core/vm: remove function call for stack validation from evm runloop * core/vm: separate gas calc into static + dynamic * core/vm: optimize push1 * core/vm: reuse pooled bigints for ADDRESS, ORIGIN and CALLER * core/vm: use generic error message for jump/jumpi, to avoid string interpolation * testdata: fix tests for new error message * core/vm: use 64-bit memory calculations * core/vm: fix error in memory calculation * core/vm: address review concerns * core/vm: avoid unnecessary use of big.Int:BitLen()
