Software interrupts or system calls aren't really appropriate for
zephyr, but we have an ongoing need in our test code to run a
function with arguments synchronously in interrupt context.
This patch introduces irq_offload() which allows us to do this without
separate initialization or having to manage fake IRQs in the
interrupt controller.

Move the files that *know* about the calling convention in use by the
compiler. The routines exposed by the files moved to the i386_sysV_abi
directory follow the C calling convention specified by the
i386_sysV_abi which is the default for GCC. The upstream GCC has been
enhanced to support the iamcu_ABI that is optimized for processors
that implement the IA MCU instruction set. This new ABI provides code,
data and stack size improvements on IA MCU based systems.
This change is the first step in adding support for the IA MCU
optimized toolchains to Zephyr OS
