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.

R=fbarchard@google.com
BUG=libyuv:634

Performance Gains :- (vs C vectorized)

I422ToARGBRow_MSA     : ~1.6x
I422ToRGBARow_MSA     : ~1.6x

I422ToARGBRow_Any_MSA : ~1.58x
I422ToRGBARow_Any_MSA : ~1.6x

Performance Gains :- (vs C non-vectorized)

I422ToARGBRow_MSA     : ~7x
I422ToRGBARow_MSA     : ~7x

I422ToARGBRow_Any_MSA : ~6.9x
I422ToRGBARow_Any_MSA : ~6.8x

Regarding performance measurement, We have created standalone tests which pass in row's data from a 1920x1080 filled buffer to both the C and MSA functions. And such N iterations are executed to get more accurate timings of C vs MSA.

f553db2d30 HalfFloatPlane unittest for denormal half floats 
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.

3d047196a8 Add landmine support 
After switching bots from GYP to GN, build artifacts are left that fails
the next builds. Since it's unfeasible to clean out all bot machines
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".
