Test cases used to test intrinsics

I noticed that the follow intrinsics do not appear to be functional in the 3.4
branch:

__interlockedbittestandset
__readgsqword
__interlockedbittestandset64
__stosb
__movsb
__cpuidex

I am attaching my series of test cases that I used to exhibit the
functionality.  All of the code compiles and execute just fine with cl.exe.
