Eric Christopher 0824096cc0 Temporarily revert "For X86-64 linux and PPC64 linux align int128 to 16 bytes."
until we can get better TargetMachine::isCompatibleDataLayout to compare - otherwise
we can't code generate existing bitcode without a string equality data layout.

This reverts commit r294702.

Eric Christopher 42b9248803 For X86-64 linux and PPC64 linux align int128 to 16 bytes.
For other platforms we should find out what they need and likely
make the same change, however, a smaller additional change is easier
for platforms we know have it specified	in the ABI. As part of this
rewrite some of the handling in the backends for data layout and update
a bunch of testcases.

Based on a patch by Simonas Kazlauskas!

Teresa Johnson 4b9b379172 [ThinLTO] Don't link module level assembly when importing
Module inline asm was always being linked/concatenated
when running the IRLinker. This is correct for full LTO but not when
we are importing for ThinLTO, as it can result in multiply defined
symbols when the module asm defines a global symbol.

In order to test with llvm-lto2, I had to work around PR30396,
where a symbol that is defined in module assembly but defined in the
LLVM IR appears twice. Added workaround to llvm-lto2 with a FIXME.

Fixes PR30610.
