The incorrect threads count is printed if the number of tests are less than the
number of default threads.

This is an example. lit.py reports 4 threads but actually uses 3 threads.

$ ./utils/lit/lit.py test/Analysis/BranchProbabilityInfo/
-- Testing: 3 tests, 4 threads --
PASS: LLVM :: Analysis/BranchProbabilityInfo/basic.ll (1 of 3)
PASS: LLVM :: Analysis/BranchProbabilityInfo/noreturn.ll (2 of 3)
PASS: LLVM :: Analysis/BranchProbabilityInfo/loop.ll (3 of 3)
Testing Time: 0.02s
  Expected Passes    : 3
