Add a missing ref count bump in DecomposeLclFld.
DecomposeLclFld transforms a single lclFld node into two lclFld nodes
that reference the same lclVar, but was missing a corresponding ref
count bump. This was causing a failure in JIT/Methodical/fp/exgen/10w5d_cs_do
under JITStress=1 and JITStress=2.
