8056039: Hotspot does not compile with clang 3.4 on Linux

[vieiro]

Almost clean backport of JDK-8056039 that removes local_vsnprintf from the codebase, making it easier to build with clang.

This will make it easier to backport JDK-8369226 to restore MacOS/GHA builds, which are now failing.

Backport is not clean because the changes in vm/utilities/globalDefinitions_gcc.hpp are already in place since this commit for JFR.

Passes tier1 tests on Linux but for usual suspeccts.

Windows and MacOS GHA builds fail, but are unrelated.
