Subject: [PATCH, tree-optimization]: Fix PR46346

Hello!

Various tests fail with -mfma with: internal compiler error: in
rhs_to_tree, at tree-ssa-forwprop.c:352. Attached patch adds missing
GIMPLE_TERNARY_RHS handling to rhs_to_tree.

	PR tree-optimization/46346
	* tree-ssa-forwprop.c (rhs_to_tree): Handle GIMPLE_TERNARY_RHS.

Patch was regression tested on x86_64-pc-linux-gnu. Additionally, it
fixes ICE on x86 with -mfma, reported in [1].

OK'd by richi in the PR, committed to mainline SVN.
