[Bug middle-end/18265] New: unititlized warning and SRA give confusing names

["nathan at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The attached test case, when compiled with '-O2 -Wall' gives the
following warning,

sra.i: In function 'foo':
sra.i:8: warning: 'a$m' is used uninitialized in this function

A user will know nothing of SRA and think 'I have no variable called a$m -- heck
that's not even a valid name'.

Why can't the SRA names use '.' rather than '$' as the separator?
