From-SVN: r225200

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.

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.
