Remove newly unused function and variable in tree-sra

Remove newly unused function and variable in tree-sra

Hi,

Martin and his clang warnings discovered that I forgot to remove a
static inline function and a variable when ripping out the old IPA-SRA
from tree-sra.c and both are now unused.  Thus I am doing that now
with the patch below which I will commit as obvious (after including
it in a round of a bootstrap and testing on an x86_64-linux).

Thanks,

Martin
