LiveDebugValues: Assume calls never clobber SP.
A call should never modify the stack pointer, but some backends are
not so sure about this and never list SP in the regmask. For the
purposes of LiveDebugValues we assume a call never clobbers SP. We
already have a similar workaround in DbgValueHistoryCalculator (which
we hopefully can retire soon).
This fixes the availabilty of local ASANified variables on AArch64.
