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 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 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 testfloat.do in the sim directory. Change the TEST_SIZE="all" to the
test. The best way to do this is to comment out each item out with specific test you want to run. For example, if you want to run only
the // comment option in SV. For example, binary16, you should set this variable to TEST_SIZE="HP".

4b.) If you want to turn off the generation of wlf files while running
sim-testfloat-batch, you can modify testfloat.do in the sim
directory. Inside this DO file, modify the WAV file to 0 --> i.e.,
set "quietly set WAV 0;"
