IA MCU psABI support: testsuite
We run Intel MCU psABI tests on Linux/ia32 with -miamcu. Since Intel
MCU psABI has a different calling convention, the only Linux libc function
allowed is "abort".
asm-support.S contains some support functions as well as a subset of
soft-fp, which is written in assembly with x87 instructions, to provide
intrinsics needed by -miamcu so that Intel MCU psABI tests can run on
Linux.

Wunused-parameter warnings are given from cgraph::finalize_function,
which is the middle-end. This is an oddity compared to other
-Wunused-* warnings. Moreover, Fortran has its own definition of
-Wunused-parameter that conflicts with the middle-end definition.
This patch moves the middle-end part of Wunused-parameter to the C/C++
FEs. I'm not sure if other FEs expected this warning to work. If so,
they do not seem to test for it. Ada, for example, explicitly disables
it.

[Patch ARM] Fix thinko in use of TARGET_UNIFIED_ASM
While paving the way to turn on unified syntax in ARM state I came
across this use of TARGET_UNIFIED_ASM that really doesn't make sense.
The idea that pop has different encoding sizes is a property of the
Thumb instruction set rather than a property of which form of unified
syntax was used. I still have quite a large patch set for the unified
asm switch but it seems useful to get this one out of the way to catch
any other issues.
Tested with an appropriate set of multilibs on arm-none-eabi /
applied. Bootstrapped on armhf.
