6ffe910a7e sim: move from common.m4 to SIM_AC_COMMON
Now that the sourceware tree generally requires autoconf-2.64, update
the sim tree to require that too.

This allows us to drop the long standing SIM_AC_COMMON/common.m4
workaround as autoconf 2.64+ seems to work for me.

66f8d9935e sim: dv-cfi: include stdbool.h
The dv-cfi code uses the bool type but doesn't include the stdbool.h
header.  I didn't notice for Blackfin targets as the core Blackfin
header will include stdbool.h, but most targets don't do this.

Shell code before AC_INIT will be silently culled, and since the common

90e13d65c1 sim: bfin: handle large shift values with accumulator shift insns
When the shift magnitude exceeds 32 bits, the values rotate around (since
the hardware is actually a barrel shifter).  So handle this edge case,
update the corresponding AV bit in ASTAT which was missing previously,
and tweak the AZ setting based on how the hardware behaves.

99dcc4dc65 sim: bfin: handle odd shift values with shift insns
The shift magnitude is a 5-bit signed value.  When it is between 0 and
15, then we do the requested shift, but when it is outside of that, we
have to do the opposite.

That means we flip between lshift and ashiftrt to match the hardware.

ef26d60eba sim: bfin: fix sign extension in dsp insns with MM flag
After testing the hardware with all the different dsp flags, the MM flag
triggers sign extension in all modes.  So drop the limited use of it, and
the local custom helper that was also extending unsigned values.  We also
can see that the flag checks in the mult/mac insns have the same behavior
with sign extending, so add a helper func to keep the logic the same in
both places.

This patch improves the error message when an invalid option is

being detected.
