Simon Pilgrim 91bb437eb8 [AARCH64] Enable AARCH64 lit tests on windows dev machines
As discussed on PR27654, this patch fixes the triples of a lot of aarch64 tests and enables lit tests on windows

This will hopefully help stop cases where windows developers break the aarch64 target

; The target lowering for integer comparisons was replacing some DAG nodes
; during operation legalization, which resulted in dangling pointers,
; cycles in DAGs, and eventually crashes. This is the testcase for
; one of those crashes. (rdar://10653656)
