[ELF] Move `// REQUIRES:` line to the top llvm-svn: 335676

// REQUIRES: arm
[ELF] Add R_ARM_RELATIVE to relocations that can be applied to GotSection When compiling -fpie and linking with the --pie option the R_ARM_GOTBREL relocation to D is resolved by writing the value of D into the .got slot and emitting an R_ARM_RELATIVE relocation for it. This changes adds the R_ARM_RELATIVE relocation to the switch in relocateOne() so we can process the GotSection relocation to write the value of the variable as well as emitting the dynamic relocation.

[ELF] - Do --hash-style=both by default. Its PR34712, GNU linkers recently changed default values to "both" of "sysv". Patch do the same for all targets except MIPS, where .gnu.hash section is not yet supported. Code suggested by Rui Ueyama. Differential revision: https://reviews.llvm.org/D38407 llvm-svn: 315051

ELF: Place relro sections after non-relro sections in r/w segment. This is in preparation for my next change, which will introduce a relro nobits section. That requires that relro sections appear at the end of the progbits part of the r/w segment so that the relro nobits section can appear contiguously. Because of the amount of churn required in the test suite, I'm making this change separately. llvm-svn: 291523
