ELF: Implement basic support for --version-script. This patch only implements support for version scripts of the form: { [ global: symbol1; symbol2; [...]; symbolN; ] local: *; }; No wildcards are supported, other than for the local entry. Symbol versioning is also not supported. It works by introducing a new Symbol flag which tracks whether a symbol appears in the global section of a version script. This patch also simplifies the logic in SymbolBody::isPreemptible(), and teaches it to handle the case where symbols with default visibility in DSOs do not appear in the dynamic symbol table because of a version script. Fixes PR27482. Differential Revision: http://reviews.llvm.org/D19430 llvm-svn: 267208

[ELF] Remove -m argument to lld in test files. NFC. This should be correctly implied by the linker. This also makes the tests slightly easier to maintain and compare with the equivalent tests under for other platforms. Differential Revision: https://reviews.llvm.org/D47513 llvm-svn: 333567

Reland "Change the X86 datalayout to add three address spaces for 32 bit signed, 32 bit unsigned, and 64 bit pointers." This reverts 57076d3199fc2b0af4a3736b7749dd5462cacda5.
