Add checks for missing SSA numbers (#57274)

In several places there were cases where we were checking lvaInSsa for
the lcl num of a local tree node, but then proceeded to use the ssa
number directly after. It is possible for a local to be in SSA without
tree nodes themselves having SSA form built for them, for example if
unreachable code makes it to SSA building. This adds some additional
check for missing SSA numbers.
