[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.

Simplify AArch64 isRelRelative This patch simplifies the isRelRelative for AArch64 and add the missing ones for bootstrap and test-suite. It also adds more testing for shared object creation. llvm-svn: 264322
