[clang] [2 of 3] Dealing with custom ast expressions and flow of types in the frontend.
Summary:
This is the second of 3 stack diffs to deal with replacing the parser of types.
This diff is about general changes to the frontend to make it cope with the change. There
are two main challenges:
1. We create pieces of ast in ast_expressions, such as getters and setters. For that we create
custom types.
2. We store types in cMethod_signature for parameters and return type of functions. This was
stored as strings, but that means losing the pointer information which is vital to get the
sil types.
So this diff consists mostly of dealing with these challenges. It change the signature of
cMethod_signature and update modules accordingly.
To deal with the custom types, we build methods in ast_expressions for creating those types,
with a custom type pointer, like "internal_typeint". At the beginning of the translation we save
all these custom types in the map from type pointers to sil types that we build as we compute the
types, so that they are available later.
Another custom type that we build is a type of classes or pointer of classes based on the current
class. I found a simple way to deal with it, giving it a pointer "class_name", and then we know
how to translate those. Something I tried is to save the declaration of the current class and pass
that declaration around, but somehow that lead to pref regression, so I removed it in favor of this
more lightweight version.
