Subject: [PATCH] [BOLT][test] Allow uninstantiated tests when no matching
 targets are enabled

When neither X86 nor AArch64 is enabled, e.g. when only enabling the
RISCV target, check-bolt-unit triggers GTest's uninstantiated suite
errors on the following cases:

        BOLT-Unit :: Core/./CoreTests/GoogleTestVerification/UninstantiatedParameterizedTestSuite<BinaryContextTester>
        BOLT-Unit :: Core/./CoreTests/GoogleTestVerification/UninstantiatedParameterizedTestSuite<MCPlusBuilderTester>
        BOLT-Unit :: Core/./CoreTests/GoogleTestVerification/UninstantiatedParameterizedTestSuite<MemoryMapsTester>
        BOLT-Unit :: Profile/./ProfileTests/GoogleTestVerification/UninstantiatedParameterizedTestSuite<PerfScriptTestHelper>

Add gated GTEST_ALLOW_UNINSTANTIATED_PARAMETERIZED_TEST to suppress such
warnings until appropriate tests have been implemented.
