Subject: Legalization of function parameter types.

This commit fixes issue #275

This commit includes following changes:

1. legalize function parameter IRParam instructions
2. legalize function parameter types in IRFuncType
3. legalize call sites (IRCall) with proper arguments
4. legalize local vars that has a mixed resource type.
