Nick Desaulniers 6b80031fa1 Revert "Revert "ANDROID: enable LLVM_IAS=1 for clang's integrated assembler for x86_64"" 
This reverts commit e9a55d9770.

Re-enables the use of LLVM_IAS=1. This was disabled in aosp/1559459 due
to a single time-based test failure. This test failure is not
reproducible locally. The failure has never been observed on newer
kernel versions either. We should consider disabling this test if we
observe further flakes.

Test: 1. apply this patch
2. build kernel image
  $ BUILD_CONFIG=common/build.config.gki.x86_64 build/build.sh && \
    BUILD_CONFIG=common-modules/virtual-device/build.config.cuttlefish.x86_64 \
    build/build.sh
3. launch cuttlefish with custom kernel image
  $ launch_cvd -kernel_path=/path/to/out/android-4.19-stable/dist/bzImage \
    -initramfs_path=/path/to/out/android-4.19-stable/dist/initramfs.img &
4. run test
  $ atest vts_ltp_test_\
    x86:syscalls.nanosleep01_32bit#syscalls.nanosleep01_32bit -- --abi x86
Test was repeated 10 times locally, 0 failures observed.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
