[llvm] r347476 - Reland test/MC/Mips/reloc-directive-label-offset.s

[Vladimir Stefanovic via llvm-commits]

New Revision: 347476

URL: http://llvm.org/viewvc/llvm-project?rev=347476&view=rev
Log:
Reland test/MC/Mips/reloc-directive-label-offset.s

The test was reverted because it failed on
llvm-clang-x86_64-expensive-checks-win builder, and that was because
-DEXPENSIVE_CHECKS adds randomness to llvm::sort(), affecting the order of
relocation table entries.
Modified the test to not have two relocations at the same offset.
