[PATCH 0/6] modifiers inheritance by '&' and 'typeof()'

[Luc Van Oostenryck <luc.vanoostenryck@gmail.com>]

There is several issues regarding which modifiers is or must be
preserved when using the '&' or 'typeof()' operators. There is
also no explicit tests for these. This serie aims to improve this
situation by:
  - avoid to inherit storage modifiers by '&' (patch 1)
  - simplify an existing test (patch 2 & 3)
  - create a bunch of test cases (patch 4 & 5)
  - partial fix for modifiers needing to be inherited by typeof
    (patch 6)

The last patch is marked as '[RFC]' because it needs some clarification
on the wanted semantics of some modifiers in some situations.
In particular, MOD_NODEREF & MOD_SAFE are for the moment not addressed,
like the address space.
Lastly, especially for what concerns MOD_SAFE, some others changes are
needed.

Luc Van Oostenryck (6):
  storage should not be inherited by pointers
  testsuite: simplify test function-pointer-inheritance
  use a shorter name for function-pointer-modifier-inheritance.c
  testsuite: test modifiers preserved by '&' operator
  testsuite: test modifiers preserved by 'typeof()'
  [RFC] some modifiers need to be preserved by 'typeof()'
