Subject: [PATCH] [SampleProfile] Skip intrinsic calls when visiting callsites
 in InlineHotFunctions.

Before this patch, we always called method 'findCalleeFunctionSamples()' on
intrinsic calls. However, intrinsic calls like llvm.dbg.value() are not viable
candidates for obvious reasons.

No functional change intended.
