Reland "Add .S and .asm files to lzma_sdk for performance improvements"

The original change was reverted due to being thought of as the
reason for crbug.com/1376525. However, upon further investigation
it was determined that this CL was not the cause.

This is a reland of commit 33c087f12620fcee0564e5ad466454e31c2d86a4

Original change's description:
> Add .S and .asm files to lzma_sdk for performance improvements
>
> Utilizing the .S and .asm files in lzma_sdk has shown to improve
> mini_installer runtime performance of about 15-20%, thanks to the
> improvements in decompression via the LzmaDecOpt implementation.
>
> crbug.com/1341436 tracks work to be able to compile the lzma ASM
> files via llvm-ml instead of having to utilize ml/ml64.exe. Once
> crbug.com/1341436 is resolved, the changes to
> //build/toolchain/win/toolchain.gni for utilizing ml/ml64.exe
> should be removed.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
