[PATCH] use local labels instead of __LINE__

Compilation with gcc (GCC) 5.0.0 20150126 of trunk gives an error in expansion
of EXPECT_DEATH(VariantValue(VariantMatcher::SingleMatcher(varDecl())) at
llvm/tools/clang/unittests/ASTMatchers/Dynamic/VariantValueTest.cpp:149 due to
the use of __LINE__ in
utils/unittest/googletest/include/gtest/internal/gtest-death-test-internal.h to
create local labels: in new gcc __LINE__ is replaced with different values and
thus the labels do not match [1].

Attached patch solves the problem by using a local label instead of __LINE__.
