## Why this should be merged
In lieu of modifications to `core.IntrinsicGas()`, required for support
of Warp in SAE.
If we were to introduce variadic `options.Option`s to `IntrinsicGas()`,
it's impossible to guarantee that they would always be passed. The
`types.Transaction` itself isn't actually passed to `IntrinsicGas()`
either, so we can't rely on it to carry payloads/hooks.
## How this works
`vm.Hooks` are extended to include `PreprocessingGasCharge(tx
common.Hash) (uint64, error)`, which returns the amount of gas to be
charged between `core.IntrinsicGas` and `vm.EVM` execution charges. The
two entry points to execution, `vm.EVM.Call()` and `vm.EVM.Create()` are
modified to first spend said charge before running upstream logic.
The new hook is defined on a separate interface definition, embedded in
`vm.Hooks`, to allow types to implement just that method and enforce it
with the `var _ vm.Preprocessor = (*impl)(nil)` pattern.
## How this was tested
Integration tests via both `core.ApplyTransaction()` and
`core.ApplyMessage()`. The former is more comprehensive, while the
latter allows for inspection of interim error values.
