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.

sim: bfin: fix dsp insns IH saturation/rounding behavior
When using the IH modifier, we need to first saturate the value before
rounding it, and then further saturate it a bit more. This makes the
sim match the hardware behavior with these insns.

py-inferior.exp: Make sure local var is allocated on the stack.
The testcase, at some point, is trying to change the contents
of a string that was defined as follow:
char *str = "hello, testsuite";
The problem is that the string is constant, and str is never used
to change the contents of the string in the program, so the compiler
is free to allocate it in a read-only section. This is what happens
on x86-windows, for instance.
As a result, trying to change the contents of the string during
the `python gdb.inferiors()[0].write_memory (addr, str)' results
in the following error:
(gdb) python gdb.inferiors()[0].write_memory (addr, str)

Traceback (most recent call last):
