Apparently we still build non-NEON variants of bionic!

This reverts commit e57d772353.

93a1f8b1f5 More printf de-duplication.
Just trivial use of macros.

The %s/%ls case in __find_arguments was backwards in the wide copy of
the code, but not problematically so because all pointers are the same
size anyway.

Josh Gao
8e13b67c64 versioner: properly handle extern "C", "C++".
extern "C" and "C++" are parsed as a LinkageSpecDecl with the real Decl
as a child node. This leads to the preprocessor sticking its guard
between the extern specifier and the declaration.

Update the AST visitor to add a special-case for calculating the
SourceRange on a LinkageSpecDecl, and add a test.

ac5603a979 Make versioner depend on lib{LLVM,clang}_android.so
Bug: http://b/64121881

The modules built in the Android tree are now named
lib{LLVM,clang}_android.so.  Let versioner depend on these temporarily
before eventually depending on the prebuilt libraries.

Test: aosp_marlin checkbuild with FORCE_BUILD_LLVM_COMPONENTS set and
unset.

Android is UTF-8. Don't make everyone pay to convert UTF-8 to ASCII just
so we can recognize '%'. With UTF-8 we can just strchr forwards.

ed9bfc4616 [AArch64] Optimized memcmp
Patch written by Wilco Dijkstra submitted for review to newlib:
https://sourceware.org/ml/newlib/2017/msg00524.html

This is an optimized memcmp for AArch64.  This is a complete rewrite
using a different algorithm.  The previous version split into cases
where both inputs were aligned, the inputs were mutually aligned and
unaligned using a byte loop.  The new version combines all these cases,
while small inputs of less than 8 bytes are handled separately.

This allows the main code to be sped up using unaligned loads since
there are now at least 8 bytes to be compared.  After the first 8 bytes,
align the first input.  This ensures each iteration does at most one
unaligned access and mutually aligned inputs behave as aligned.
After the main loop, process the last 8 bytes using unaligned accesses.

This improves performance of (mutually) aligned cases by 25% and
unaligned by >500% (yes >6 times faster) on large inputs.

The performance measured on the bionic-benchmarks on a hikey
board with a new benchmark for unaligned memcmp submitted for
review at https://android-review.googlesource.com/414860

The base is with the libc from /system/lib64. The bionic libc
with this patch is in /data.

618303ca4a More printf de-duplication.
Fix the 'j' (intmax_t/uintmax_t) length qualifier in the wide
variant. (With new tests that fail without this fix.)

Fix a typo in the wide support for intmax_t*, which isn't testable because
%n is disabled on Android (and will be removed in a later cleanup pass).

Also move the public vfprintf/vfwprint functions into stdio.cpp.

18a1957444 Add basic tests for the remaining 9 libm <fenv.h> functions.
It seems that feenableexcept/fegetexcept are lying to us on arm/arm64
because the hardware doesn't actually support such functionality. When
I get confirmation of that from ARM I'll fix the <fenv.h> implementation
correspondingly --- writing to/reading from reserved FP control register
bits as we currently do doesn't seem like the best of ideas.
