varasm: Handle RAW_DATA_CST in compare_constant [PR117199]
On the following testcase without LTO we unnecessarily don't merge
two identical .LC* constants (constant hashing computes the same hash,
but as compare_constant returned false for the RAW_DATA_CST in it,
it never compares equal), and with LTO fails to link because LTO assumes such
constants have to be merged and so doesn't emit the other constant.

* varasm.cc (compare_constant): Handle RAW_DATA_CST. Formatting fix
in the STRING_CST case.
