Julian Ganz 5241645c47 tests: add test with interrupted memory accesses on rv64 
This test aims at catching API misbehaviour w.r.t. the interaction
between interrupts and memory accesses, such as the bug fixed in

    27f347e6a1
    (accel/tcg: also suppress asynchronous IRQs for cpu_io_recompile)

Because the condition for triggering misbehaviour may not be
deterministic and the cross-section between memory accesses and
interrupt handlers may be small, we have to place our trust in large
numbers. Instead of guessing/trying an arbitrary, fixed loop-bound, we
decided to loop for a fixed amount of real-time. This avoids the test
running into a time-out on slower machines while enabling a high number
of possible interactions on faster machines.

The test program sends a single '.' per 1000000 loads/stores over the
serial. This output is not captured, but may be used by developers to
gauge the number of possible interactions.

README 

This directory contains various interesting guest binaries for
regression testing the Tiny Code Generator doing system and user-mode
emulation.

The multiarch directory contains shared code for tests that can be
built for all guest architectures. Architecture specific code can be
found in their respective directories.

System mode tests will be under the "system" subdirectories.

GDB scripts for exercising the gdbstub on specific tests will be found
under the "gdbstb" subdirectories.

See the developer guide for more instructions on "make check-tcg"
