[ELF/AArch64] Allow only valid dynamic relocations in the output. All relocations, which cannot be handled by the dynamic linker, cause a linking error "rebuild with -fPIC". Differential revision: http://reviews.llvm.org/D15193 llvm-svn: 254840

Rewrite our relocation processing. This splits relocation processing in two steps. First, analyze what needs to be done at the relocation spot. This can be a constant (non preemptible symbol, relative got reference, etc) or require a dynamic relocation. At this step we also consider creating copy relocations. Once that is done we decide if we need a got or a plt entry. The code is simpler IMHO. For example: - There is a single call to isPicRel since the logic is not split among adjustExpr and the caller. - R_MIPS_GOTREL is simple to handle now. - The tracking of what is preemptible or not is much simpler now. This also fixes a regression with symbols being both in a got and copy relocated. They had regressed in r268668 and r268149. The other test changes are because of error messages changes or the order of two relocations in the output. llvm-svn: 322047

// CHECK: relocation R_AARCH64_ADR_PREL_PG_HI21 cannot be used against symbol dat; recompile with -fPIC
Change the error message format for an incompatible relocation. Previous error message style: error: /home/alice/src/bar.c:12: relocation R_X86_64_PLT32 cannot refer to absolute symbol 'answer' defined in /home/alice/src/foo.o New error message style: error: relocation R_X86_64_PLT32 cannot refer to absolute symbol: foo >>> defined in /home/alice/src/foo.o >>> referenced by bar.c:12 (/home/alice/src/bar.c:12) >>> /home/alice/src/bar.o:(.text+0x1) llvm-svn: 299390
