This patch adds:
- VariableMode::kPrivateMethod
- VariableMode::kPrivateSetterOnly
- VariableMode::kPrivateGetterOnly
- VariableMode::kPrivateGetterAndSetter
And replace the previous RequiresBrandCheckFlag by inferring
whether the brand check is required from these VariableModes.
It is then possible to check duplicate non-complementary
accessors in the parsers and throw early errors, and allow
complementary accessors to be associated with the same
private name variable.
This patch also adds the following AssignType:
- PRIVATE_METHOD
- PRIVATE_GETTER_ONLY
- PRIVATE_SETTER_ONLY
- PRIVATE_GETTER_AND_SETTER
corresponding to the new VariableModes so that it's possible
to generate specialized code for different type of
private accessor declarations.
