[PATCH] D29170: [ELF] - Remove unnessesary checks from GC logic.

[George Rimar via llvm-commits]

>> https://reviews.llvm.org/D28612 adds SHT_RELA and SHT_REL sections that should be involved in GC (because .rela.text depends on .text and we do not want to keep REL[A] >sections unconditionally).
>> REL[A] sections are not SHF_ALLOC, that means I need to set up GC logic for them.>

Ok, I am going to split the patches then in according to what you suggesting.
I will restrict using --gc-sections and --emit-relocs for first patch. Anyways by the way it is not the case I am fixing in kernel,
it just should proccess "/DISCARD"/ correctly, --gc-sections was not involved there.
