Update sim-testfloat to fix errors due to bad config element. I am not sure of the reasoning, but the specific path to the testvector was not getting inserted in Questa. This modification also adds features to test individualized tests (.e.g, binary16 only) -- documentation is added in the FPbuild.txt file

 4a.) Each test will test all its vectors - if you want to test a
 subset of the vectors (e.g., only binary16), you should modify the
-cvw/testbench/tests-fp.h and comment out the tests  you do not want to
-test.  The best way to do this is to comment out each item out with
-the // comment option in SV.  For example,
-
-string f128div[] = '{

+binary16, you should set this variable to TEST_SIZE="HP".

+sim-testfloat-batch, you can modify testfloat.do in the sim
