Refactor the kvm_cpu_cap_init() macro magic to collect supported features
in a local variable instead of passing them to the macro as a "mask". As
pointed out by Maxim, relying on macros to "return" a value and set local
variables is surprising, as the bitwise-OR logic suggests the macros are
pure, i.e. have no side effects.
Ideally, the feature initializers would have zero side effects, e.g. would
take local variables as params, but there isn't a sane way to do so
without either sacrificing the various compile-time assertions (basically
a non-starter), or passing at least one variable, e.g. a struct, to each
macro usage (adds a lot of noise and boilerplate code).
Opportunistically force callers to emit a trailing comma by intentionally
omitting a semicolon after invoking the feature initializers. Forcing a
trailing comma isotales futures changes to a single line, i.e. doesn't
cause churn for unrelated features/lines when adding/removing/modifying a
feature.
No functional change intended.
