The following series of patches improves the handling of msp430-specific
attributes by making use of generic mechanisms for performing common
tasks (i.e. handling attribute conflicts, putting data objects in sections).
The patches also transition the msp430 back end to fully use the generic
handling of the "noinit" attribute.
Successfully bootstrapped and regtested on x86_64-pc-linux-gnu.
Successfully regtested for msp430-elf.
As a further sanity test I built GCC for arm-eabi and ran
execute.exp=noinit-attribute.c to confirm the noinit attribute still
works as expected for ARM.
Ok for trunk?
