[Qemu-devel] [PATCH 08/23] tests/tcg/xtensa: conditionalize debug option tests

[Max Filippov <jcmvbkbc@gmail.com>]

Make debug tests conditional on the presence of the debug option in the
config and tests that depend on the presence/number of instruction or
data breakpoint registers on the corresponding definitions. Use
configured debug interrupt level instead of the hardcoded value to set
up IRQ handler and access debug EPC register.
