[vm/compiler] Fix computation of ParameterInstr type in a catch block

In order to compute type, ParameterInstr::ComputeType() uses
environment index to get a LocalVariable from LocalScope,
assuming that environment index matches a variable index in the scope.
This is only true for direct parameters (which are not copied in
prologue).

This change limits use of LocalVariable type for ParameterInstr
corresponding to direct parameters. Note that it only affects
Parameter instructions used in catch block entries, as
ParameterInstr in function entry always corresponds to a direct
parameter.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
