[pushed v2 0/4] Rewrite enum_flags, add unit tests, fix problems

[Pedro Alves]

I've addressed the review comments made to v1 of this series,
originally posted at:

  https://sourceware.org/pipermail/gdb-patches/2020-August/171392.html

and merged it.

Changes in v2:

Patch #1 includes Andrew's bits, with a tweak -- I'm calling the new
method type::instance_flags() instead of type::get_instance_flags() to
follow the same scheme of the other getters/setters.  That required
renaming the type::instance_flags data field.  And since we now have
the methods, I got rid of SET_TYPE_INSTANCE_FLAGS and just used the
method directly throughout.

Patch #2 is new, to address a comment from Tromey.

Patch #3 is unmodified.

Patch #4 includes the fix that disables the rvalue ref compound
assignemnt operators.

Pedro Alves (4):
  Use type_instance_flags more throughout
  Rename address_space_int_to_name/address_space_name_to_int
  Rewrite valid-expr.h's internals in terms of the detection idiom
    (C++17/N4502)
  Rewrite enum_flags, add unit tests, fix problems
