This patch implements timeit timing tool found at tools/timeit.c for Windows.
It is required for compile time and run time calculations by the llvm-testsuite.
At this moment llvm testsuite tests can not be compiled with clang-cl MSVC combination
however we have also made required modifications to the cmake files to enable building
timeit on windows with clang-cl/cl.
In developer console with MSVC following command can be used to successfully build this code:
set CC=c:\work\llvm-dev\build\bin\clang-cl.exe
set CXX=c:\work\llvm-dev\build\bin\clang-cl.exe
cmake -G Ninja -DTEST_SUITE_SUBDIRS= ..\llvm-test-suite
