Trying to build MySQL 5.5.1-m2 with gcc 4.5.0 svn 156081 and lto enabled
results in:

lto1: internal compiler error: in ipcp_iterate_stage, at ipa-cp.c:759
Please submit a full bug report,
with preprocessed source if appropriate.


Not sure how to generate a meaningful preprocessed source for LTO bits -- does
it come down to adding the preprocessed source for all listed source files?

The process is to indeed do that, but you can reduce to less files by (assuming
it ICEs during link stage) linking with -r and omit as many object files as
possible.  Only preprocessed source for the remaining files are needed
(usually two to three).
