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

// REQUIRES: arm
Initial support for the local dynamic model ARM TLS relocations: - R_ARM_TLS_LDM32 - R_ARM_TLS_LDO32 The local dynamic implementation and tests follows the same model as the other ARM TLS models. The R_ARM_TLS_LDO32 is implemented as R_ABS expr type as the getVA() for a TLS symbol will return the offset from the start of the TLS block.

[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

[test] Change llvm-readobj -long-option to --long-option or well-known short options. NFC Also change some options that have different semantics (cause confusion) in llvm-readelf mode: -s => -S -t => --symbols -sd => --section-data llvm-svn: 359651
