    Add parseExpr and compileParsedExpr and use them in GHC API and GHCi
    
    Summary:
    This commit brings following changes and fixes:
    
     * Implement parseExpr and compileParsedExpr;
     * Fix compileExpr and dynCompilerExpr, which returned `()` for empty expr;
     * Fix :def and :cmd, which didn't work if `IO` or `String` is not in scope;
     * Use GHCiMonad instead IO in :def and :cmd;
     * Clean PrelInfo: delete dead comment and duplicate entries, add assertion.
    
    See new tests for more details.
    
    Test Plan: ./validate
