[PATCH] D38846: [ELF] - Linkerscript: Fix issues with SUBALIGN.

[George Rimar via Phabricator via llvm-commits]

grimar created this revision.

This is PR34886.
We have 2 issues with SUBALIGN command:

1. Expression must be constant, so should not allow using Dot.
2. If expression result is zero we assert.

Patch fixes both. I checked that bfd allows SUBALIGN(0),
so I think we should do the same. Fix here is consistent with other places
in LLD.
