[PATCH] D151406: [Hexagon] Check if register is non-null before calling subregs_inclusive

[Sergei Barannikov via Phabricator via llvm-commits]

barannikov88 added a comment.

This is a workaround to fix these failures (caused D151036 <https://reviews.llvm.org/D151036> to be reverted):
https://lab.llvm.org/buildbot/#/builders/38/builds/12037

This patch preserves the behavior, NFCI.
It should probably skip debug instructions instead, but I don't know how to prepare test for that.
