[8u] RFA+RFR (S) 8214189: test/hotspot/jtreg/compiler/intrinsics/mathexact/MulExactLConstantTest.java fails on Windows x64 when run with -XX:-TieredCompilation

[Aleksey Shipilev]

Original bug:
  https://bugs.openjdk.java.net/browse/JDK-8214189

Original fix:
  http://hg.openjdk.java.net/jdk/jdk/rev/0037ea3c7322

Patch does not apply to 8u cleanly and needs manual merge. It seems 8u code has "unsigned int"
instead of "unsigned long" in modified locations. New test does not fail with unfixed 8u, so I
wonder if this patch is needed in 8u, Roland?

Test also moved to proper location in 8u. ProblemList change does not apply to 8u as well. Christoph
handles 11u backport.

8u webrev:

Testing: {Windows, Linux} x86_64 build, test/compiler/integerArithmetic/

Thanks,
