Hi all,

could you please review the changset which update jvmci tests to use vm.jvmci @requiers property instead of cpu architecture bases expressions?

there are two cases: 
 - jvmci tests which can be run on all platforms which support jvmci, in these tests '(vm.simpleArch == "x64" | vm.simpleArch == "sparcv9" | vm.simpleArch == "aarch64”)’ was replaced by vm.jvmci
 - test/compiler/jvmci/jdk.vm.ci.code.test tests which require an arch specific subclass of TestAssembler class, for the time being, there are only amd64 and sparc versions. in such tests @requires expression was changed to 'vm.jvmci & (vm.simpleArch == "x64" | vm.simpleArch == "sparcv9”)'

please be aware, this fix depends on 8170226 which adds vm.jvmci property.
