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.

Add support for Intel PKRU register to GDB and GDBserver. This patch adds support for the registers added by the Memory Protection Keys for Userspace (PKU aka PKEYs) feature. Native and remote debugging are covered by this patch. The XSAVE area is extended with a new state containing the 32-bit wide PKRU register. The new register is added to amd64-avx-mpx_avx512-* tdesc, thus it is renamed accordingly. Also, respective xstate mask X86_XSTATE_AVX_MPX_AVX512_MASK is renamed to X86_XSTATE_AVX_MPX_AVX512_PKU_MASK to reflect the new feature set it supports.

<!-- I386 with AVX, MPX, AVX512, PKEYS - Includes Linux-only
special "register". -->
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.

Add support for Intel PKRU register to GDB and GDBserver. This patch adds support for the registers added by the Memory Protection Keys for Userspace (PKU aka PKEYs) feature. Native and remote debugging are covered by this patch. The XSAVE area is extended with a new state containing the 32-bit wide PKRU register. The new register is added to amd64-avx-mpx_avx512-* tdesc, thus it is renamed accordingly. Also, respective xstate mask X86_XSTATE_AVX_MPX_AVX512_MASK is renamed to X86_XSTATE_AVX_MPX_AVX512_PKU_MASK to reflect the new feature set it supports.

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.
