[lto] fix reading of CALL_EXPRs

[Nathan Froyd]

The patch below fixes an issue with reading in CALL_EXPRs.  We
weren't setting the type of the newly-created CALL_EXPR, which caused
segfaults later on.

With this patch, we can now process a simple factorial example with
lto1.

Patch approved by Kenny on IRC and committed.
