v3_core: Suppress compiler-generated calls in guards
Compiling the following function:
f(V) when not (bar and V) -> true; %Line 4
f(_) -> false.
would produce the following warnings:
no_file: Warning: the call to is_boolean/1 has no effect
t.erl:4: Warning: the guard for this clause evaluates to 'false'
t.erl:4: Warning: use of operator '=:=' has no effect
Two of the warnings refer to calls to is_boolean/1 and '=:='/2 which
v3_core added when translating the code to Core Erlang. The only
relevant warning is:
t.erl:4: Warning: the guard for this clause evaluates to 'false'
Suppress the other two warning by marking the compiler-generated
calls with a 'compiler_generated' annotation.
