[PATCHv3 1/9] gdb/gdbarch: remove unused 'invalid=True' from gdbarch_components.py

[Andrew Burgess <aburgess@redhat.com>]

Due to the algorithm used to generate verify_gdbarch in gdbarch.py, if
a component has a predicate, then a validation check will never be
generated.

There are a bunch of components that are declared with both a
predicate AND have 'invalid=True' set.  The 'invalid=True' has no
effect.

In this commit I clean things up by removing all these additional
'invalid=True' lines.  There's no change in any of the generated files
after this commit.
