Add support for SHF_ARM_PURECODE. Now we don't mark a PT_LOAD as readable if all its sections are SHF_ARM_PURECODE. llvm-svn: 326207

[lld] Mitigate relocation overflow [part 1 of 2]. This CL places .dynsym and .dynstr at the beginning of SHF_ALLOC sections. We do this to mitigate the possibility that huge .dynsym and .dynstr sections placed between ro-data and text sections cause relocation overflow.
