Summary: public
Type of `this` argument to c++ method call has pointer type.
It's either raw pointer (for `->`) or reference (for `.`).
It was already correct in method declaration and method parameters, but it wasn't correct in method calls. Same thing will apply to constructor expressions.
As a result of this change, we won't expand type when calling methods.
Change to ast_expressions.ml fixes problem with autogenerating getters/setters that produced lvalue types after LValueToRValue cast.

Summary: public
Adding initial support for Buck for Cxx on the toplevel infer command.
If a `cxx_binary`/`cxx_library` builds with the command `buck build //targetName:target` then the analysis of Infer can be triggered through the `#infer` flavor.
This change configures buck to run Infer, whenever the `#infer` flavor gets passed: just run
`infer --use-flavors -- buck build //targetName:target#infer`
Please note that when using this feature (`--use-flavors`), the toplevel `infer` command has to be launched from the root of the buck project (which is where the `.buckconfig` file is located) and the `#infer` flavor must be passed on the target.

Summary: public Translate classes and protocols on demand only.
This saves space in the tenv and time. The categories still cannot be translated on demand
because there is no pointer to them from the classes. Andrzej is fixing that.
We had to make cTypes_Decl and the modules for translating classes, protocols and categories mutually
recursive. Moreover, we had to reorder the method for adding classes to the tenv to receive a decl and
return a type.

Since file is relative path, type name can have '/' in its name.
This is very fragile since we might create file wiht typename in its name (for example for methods).
Replacing '/' with '_' should make frontend more resilient to failure.
Translation of anonymous structs is still pretty fragile (due to relative path in its name),
but at least it doesn't crash frontend

2. shell commands:
grep '^val ' infer/src/backend/iList.mli | cut -f 2 -d ' ' | tr '\n' ' '
# gives a list of former list_ functions that IList implements, fed into the loops below:
LISTNAMES=" compare equal append combine exists filter flatten flatten_options find fold_left fold_left2 for_all for_all2 hd iter iter2 length fold_right map mem nth partition rev rev_append rev_map sort split stable_sort tl drop_first drop_last rev_with_acc remove_duplicates remove_irrelevant_duplicates merge_sorted_nodup intersect mem_assoc assoc map2 to_string"
# replace " list_*" function calls with IList.* ones
for i in $LISTNAMES; do find . -name '*.ml' -exec sed -i -e "s/ list_$i\b/ IList.$i/g" \{\} \; ; done
# replace (list_* functions with (IList.* ones
for i in $LISTNAMES; do find . -name '*.ml' -exec sed -i -e "s/(list_$i\b/(IList.$i/g" \{\} \; ; done
# ditto with [
for i in $LISTNAMES; do find . -name '*.ml' -exec sed -i -e "s/\[list_$i\b/[IList.$i/g" \{\} \; ; done
3. Then fix up the rest by hand. In particular, stuff that called Utils.list_*
explicitely, and stuff that used the "Fail" exception that has moved to
IList. (may revisit this in the future)
