This patch reland 54c1a9b20d89e85cd60d002c77b34c00f36520f4, which
updates GoogleTest to v1.14.0. This patch fixes bots failures caused
by the early patch.
This reverts commit 59052468c3e38cab15582cefbb5133fd4c2ffce5.
It looks like this patch breaks the build when compiler-rt is passed to
LLVM_ENABLE_PROJECTS instead of LLVM_ENABLE_RUNTIMES.
This will help improve the project's layering, so that sub-projects
that don't actually need any llvm code can still use googletest
without having to reference code in the llvm directory.
This will also make it easier to consolidate and simplify the standalone
build configurations.
