commit 8a8b3a6ad25f6bd379f7cbd6cc1f9edcf076d940
Author: John Baldwin <jhb@FreeBSD.org>
Date: Tue Mar 22 12:05:43 2022 -0700
Remove USE_SIGTRAP_SIGINFO condition for FreeBSD/x86 debug regs support.
For BSD x86 targets, stopped_by_hw_breakpoint doesn't check siginfo_t
but inspects the DR6 register directly via PT_GETDBREGS.
(cherry picked from commit 711b0b6698ff6350b7c61710491c76c749945d4a)
