[ELF] Set EF_ARM_EABI_VER5 for ARM Without this flag set, an AArch64 Linux kernel won't try to load the executable (even if a 32 bit arm kernel will run the binary just fine). Patch by Martin Storsjö! Differential revision: https://reviews.llvm.org/D24471 llvm-svn: 281394

[ELF][ARM] Implement support for Tag_ABI_VFP_args The Tag_ABI_VFP_args build attribute controls the procedure call standard used for floating point parameters on ARM. The values are: 0 - Base AAPCS (FP Parameters passed in Core (Integer) registers 1 - VFP AAPCS (FP Parameters passed in FP registers) 2 - Toolchain specific (Neither Base or VFP) 3 - Compatible with all (No use of floating point parameters) If the Tag_ABI_VFP_args build attribute is missing it has an implicit value of 0. We use the attribute in two ways: - Detect a clash in calling convention between Base, VFP and Toolchain. we follow ld.bfd's lead and do not error if there is a clash between an implicit Base AAPCS caused by a missing attribute. Many projects including the hard-float (VFP AAPCS) version of glibc contain assembler files that do not use floating point but do not have Tag_ABI_VFP_args. - Set the EF_ARM_ABI_FLOAT_SOFT or EF_ARM_ABI_FLOAT_HARD ELF header flag for Base or VFP AAPCS respectively. This flag is used by some ELF loaders.
