Mark Johnston 75cb949228 arm64/vmm: Add breakpoint and single-stepping support ... This will be used to implement parts of bhyve's gdb stub. Three VM capabilities are added, similar to amd64 without monitor mode. Two cause breakpoint and single-step exceptions to be raised to EL2 and then down to bhyve. One lets the gdb stub mask hardware interrupts while single-stepping, since otherwise the guest will handle a timer interrupt before executing the target instruction and thus fail to make progress.
