It seems older and non-multiarach aware GDBs might not fail gracefully
when faced with something they don't know. For example when faced with
a target XML for s390x the Ubuntu 18.04 gdb will generate an internal
fault and prompt for a core dump.
Work around this by invoking GDB in a more batch orientated way and
then trying to filter out between test failures and gdb failures.

break_dependency incorrectly handles the case of dependency on an opcode
that references the same register multiple times. E.g. the following
instruction is translated incorrectly:
{ or a2, a3, a3 ; or a3, a2, a2 }
This happens because resource indices of both dependency graph nodes are
incremented, and a copy for the second instance of the same register in
the ending node is not done.
Only increment resource index of the ending node of the dependency.
Add test.

Bare tests are standalone assembly tests that don't require linking to

Make timer/CCOUNT tests conditional on the presence of timer option and
number of configured timers. Don't use hard coded interrupt levels for
timers, use configured values.

Make interrupt tests conditional on the presence of interrupt option and
on the presence of level-1 and high level software interrupts. Don't use
hard-coded interrupt level for the high level interrupt tests, choose
high level software IRQ and use its configured level.

Make tests for optional instruction groups conditional on the presence
of corresponding options in the config.

Make data/instruction tests conditional on the presence of
data/instruction cache, whether they're lockable and whether data cache
is writeback.

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.

Uncomment test_boolean in the test makefile. Make actual tests code
conditional on the presence of boolean option in the config.

Use bbci.l/bbsi.l instead of bbci/bbsi, as they are assembly macros that
accept little-endian bit number and produce correct immediate for both
little and big endian configurations. Choose value loaded into register
for bbc/bbs opcodes based on configuration endianness.

Don't use 'loop' opcode in generic testsuite completion code, only use
core opcodes to make it work with any configuration.

Configurations with LITBASE register may use absolute literals by
default. Pass --no-absolute-literals option to assembler to use
PC-relative literals instead.

Configurations w/o vecbase may have vectors not grouped together and not
in fixed order. They may not always be grouped into single output
sections by assigning next offset to dot, as it may sometimes move dot
backwards and sometimes they may even belong to different memory region.
Don't group vectors into single output section. Instead put each vector
into its own section ant put it at its default virtual address.
Reserve 4KBytes from the default vectors base and put rest of the code
and data starting from there. Mark vectors sections as executable,
otherwise their contents is discarded. There may be as little as 16
bytes reserved for some vectors, load handler address into a0 and use
ret.n to jump there to make vector code fit into this 16 byte space.

When test suite with multiple tests fails it's not obvious which test
failed. Pring "failed" in every invocation of test_fail. Do printing
when DEBUG preprocessor macro is defined.

Add tests for MSA integer max/min instructions. This includes
following instructions:
* MAX_A.B - maximum of absolute of two signed values (bytes)
* MAX_A.H - maximum of absolute of two signed values (halfwords)
* MAX_A.W - maximum of absolute of two signed values (words)
* MAX_A.D - maximum of absolute of two signed values (doublewords)
* MIN_A.B - minimum of absolute of two signed values (bytes)
* MIN_A.H - minimum of absolute of two signed values (halfwords)
* MIN_A.W - minimum of absolute of two signed values (words)
* MIN_A.D - minimum of absolute of two signed values (doublewords)
* MAX_S.B - maximum of two signed values (bytes)
* MAX_S.H - maximum of two signed values (halfwords)
* MAX_S.W - maximum of two signed values (words)
* MAX_S.D - maximum of two signed values (doublewords)
* MIN_S.B - minimum of two signed values (bytes)
* MIN_S.H - minimum of two signed values (halfwords)
* MIN_S.W - minimum of two signed values (words)
* MIN_S.D - minimum of two signed values (doublewords)
* MAX_U.B - maximum of two unsigned values (bytes)
* MAX_U.H - maximum of two unsigned values (halfwords)
* MAX_U.W - maximum of two unsigned values (words)
* MAX_U.D - maximum of two unsigned values (doublewords)
* MIN_U.B - minimum of two unsigned values (bytes)
* MIN_U.H - minimum of two unsigned values (halfwords)
* MIN_U.W - minimum of two unsigned values (words)
* MIN_U.D - minimum of two unsigned values (doublewords)
Each test consists of 80 test cases, so altogether there are 1920
test cases.
