[PATCH] D41246: [LLD][ELF] Optimize Arm PLT entries

[Peter Smith via Phabricator via llvm-commits]

I've implemented the suggestion to choose the form of PLT entry based on whether the offset to the .got.plt can be represented by the shorter encoding. To maintain 16-byte alignment of the entries I've increased the size of the header to 32-bytes. As the --long-plt doesn't do anything any more I've updated all the tests to use the new encoding. Apologies for the size of the diff.
