Hi,
this patch fixed -fprofile-use ICE where call_stmt_size is 0 while it should be non-zero.
This is becuase of cgraph_merge_profiles using get_body that applies transformations
and kills the profile. This is not intended to happen.

Bootstrapped/regtested x86_64-linux, will commit it shortly.

	* ipa-utils.c (cgraph_merge_profiles): Use get_untransformed_body.
