Compile time detection has been added for whether a client was compiled with AVX-512. In this case, and if DynamoRIO is not deployed via "earliest" inject, we initialize the lazy AVX-512 code detection to true, in order to prevent the client from clobbering potential AVX-512 application state.
Adds two new tests to check for the initialized state of AVX-512 lazy code detection.
Provides support for zmm context in get_xmm_vals().
Provides support to dump zmm SIMD mcontext state. No tests for this have been added as this is used for log files.
