Add AVX512 registers support to GDB and GDBserver. This patch adds support for the Intel(R) Advanced Vector Extensions 512 (Intel(R) AVX-512) registers. Native and remote debugging are covered by this patch. Intel(R) AVX-512 is an extension to AVX to support 512-bit wide SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31). The number of available registers in 32-bit mode is still 8 (XMM0-7, YMM0-7, ZMM0-7). The lower 256-bits of the ZMM registers are aliased to the respective 256-bit YMM registers. The lower 128-bits are aliased to the respective 128-bit XMM registers. There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit mode and 64-bit mode. For more information please see Intel(R) Developer Zone: Intel(R) AVX http://software.intel.com/en-us/intel-isa-extensions#pid-16007-1495 Intel(R) Architecture Instruction Set Extensions Programming Reference: http://software.intel.com/en-us/file/319433-017pdf 2014-04-24 Michael Sturm <michael.sturm@mintel.com> Walfred Tedeschi <walfred.tedeschi@intel.com> * amd64-linux-nat.c (amd64_linux_gregset32_reg_offset): Add AVX512 registers.
