[VPlan] Replace remaining use of needsScalarIV. 
All information is already available in VPlan. Note that there are some
test changes, because we now can correctly look through instructions
like truncates to analyze the actual users.

2e14900db9 [test][NewPM] Use -passes=loop-vectorize instead of -loop-vectorize 
Update a bunch of loop-vectorize regression tests to use the new PM
syntax (opt -passes=loop-vectorize) instead of the deprecated legacy
PM syntax (opt -loop-vectorize).
