AVX-512 introduces 16 new YMM registers, as well as 32 ZMM registers.  These are already in our X86 target register description file, so our code generator was trying to use them, and then failing to find a mapping to the corresponding CodeView registers when emitting debug info.  I pulled these values from the latest version of `cvconst.h` that ships with the DIA SDK.  After making this change, I can recompile an application which was previously crashing, and it no longer crashes.
