13299e6c57 Clean up libyuv's codereview.settings 
This is a trivial change intended to test libyuv's new CQ, but also
happens to be a nice cleanup, removal of dead entries, and sort of
the remaining entries.

dbee5e2a9f Add a CQ to libyuv 
This adds a commit queue for libyuv. The set of bots triggered
is the same as the set previously specified in PRESUBMIT.py. This
has two advantages over the current setup:
a) You get nice features in Gerrit (like a dry run button); and
b) You get a CQ!

a7c87e19f0 add Intel Code Analyst markers 
add macros to enable/disable code analyst around blocks of code.

Normally these macros should not be used, but if performance
details are wanted for intel code, enable them around the code
and then run via the iaca tool, available on the intel website.

c2073823b4 use __OPTIMIZE__ macro to determine debug vs release. 
Debug builds of x86 gcc/clang can run out of register.
Previously NDEBUG or _DEBUG was used to detect a debug build.
But those macros are not set by gentoo builds.
This CL switches to the compiler predefine __OPTIMIZE__ which is
built into clang and gcc.

Halffloats have a limited range.  It shouldnt normally come up, but if the scale value passed in produces a small value, the half floats will be denormals, which are slow and/or flust to zero.  This test ensures they behave the same in C and SIMD and tests the performance of denormals.

After switching bots from GYP to GN, build artifacts are left that fails

it's better to have an automated system for this, which is what landmines is.

By adding a line to tools/get_landmines.py it is possible to clobber each bot
that syncs past that "landmine CL".
