rust-target-config: Update the data layout for x86-64 target

Browse Source 
The data layout for x86-64 target was different in rust from llvm.
It resulted in the following data layout error:
--------------------------------------------------------------------------------------
error: data-layout for target `x86_64-linux`, `e-m:e-i64:64-f80:128-n8:16:32:64-S128`,
differs from LLVM target's `x86_64-unknown-linux-gnu` default layout,
`e-m:e-p270:32:32-p271:32:32-p272:64:64-i64:64-i128:128-f80:128-n8:16:32:64-S128`
--------------------------------------------------------------------------------------

The issue was reported in meta-rust layer as:
https://github.com/meta-rust/meta-rust/pull/442

Hence, the data layout for x86-64 is modified as per the llvm sources which fixes the issue.

After running the testsuite with the modified data layout; it was observed that the
"tests/codegen/i128-x86-align.rs" passed. The modified data layout fixed the scalar pair which
resolved the testcase failure. Hence, the testcase has been removed from the exclude list.
