[PATCH 89/89] linux-user: Remove struct target_pt_regs from target_syscall.h

[Richard Henderson <richard.henderson@linaro.org>]

This structure is unused, and would only ever be used for the
ptrace syscall, which we will never implement for linux-user.

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
