[ELF][test] Reorganize some AArch64 tests Delete aarch64-got.s because it is covered by aarch64-tls-iele.s Merge got-aarch64.s into aarch64-fpic-got.s by adding disassembly to the latter Create aarch64-gnu-ifunc-nonpreemptable to unify aarch64-gnu-ifunc3.s (position-dependent executable) and aarch64-gnu-ifunc-address-pie.s (PIE) Rename aarch64-got-reloc.s to aarch64-got-weak-undef.s Add --no-show-raw-insn to llvm-objdump -d RUN lines Add -pie test to arch64-tls-iele.s Delete aarch64-tls-pie.s: it is covered by arch64-tls-iele.s and aarch64-tls-le.s Rename aarch64-copy2.s to aarch64-nopic-plt.s: "copy2" gives false impression that the test is related to copy relocation llvm-svn: 362294

[ELF][AArch64] Allow PT_LOAD to have overlapping p_offset ranges Ported the D64906 technique to AArch64. It deletes 3 alignments at PT_LOAD boundaries for the default case: the size of an aarch64 binary decreases by at most 192kb. If `sh_addralign(.tdata) < sh_addralign(.tbss)`, we can potentially make `p_vaddr(PT_TLS)%p_align(PT_TLS) != 0`. ld.so that are known to have problems if p_vaddr%p_align!=0: * musl<=1.1.22 * FreeBSD 13.0-CURRENT (and before) rtld-elf arm64 New test aarch64-tls-vaddr-align.s checks that our workaround makes p_vaddr%p_align = 0.
