Reduce removal of nonbuildable statements

[0xPhaze]

I see a few examples of where the exception list could be refined, however some might require some static analysis.
We could include exceptions for .function in vm.function and abi.function. With further analysis .Struct for Interface.Struct shouldn't be removed as well as .function in contract.function.

test/Test.t.sol:4457:11-4457:45: `.assume(_relayer > address(0x09));` nonbuildable
test/Test.t.sol:4458:9-4458:40: `vm.assume(_oracle != _relayer);` passed

Looking at your output, I think I see a bug:

test/Test.t.sol:4457:11-4457:45: `.assume(_relayer > address(0x09));` nonbuildable

Removing a method call is not supposed to remove a trailing semicolon.

Fixing that bug should eliminate at least some nonbuildable outcomes. 😬

Version 0.2.1 should address some of these problems.
