Subject: [PATCH 1/2] tools/memory-model: Remove redundant initialization in
litmus tests

Subject: [PATCH 1/2] tools/memory-model: Remove redundant initialization in litmus tests
This is a revert of commit 1947bfcf81a9 ("tools/memory-model: Add types
to litmus tests") with conflict resolutions.
klitmus7 [1] is aware of default types of "int" and "int*".
It accepts litmus tests for herd7 without extra type info unless
non-"int" variables are referenced by an "exists", "locations",
or "filter" directive.
[1]: Tested with klitmus7 versions 7.49 or later.
Suggested-by: Paul E. McKenney <paulmck@...nel.org>
