When converting from lsb 10 bit formats to msb, the values
need to be shifted to the top 10 bits. Using a multiply
allows the different numbers of bits to be copied:
// 128 = 9 bits
// 64 = 10 bits
// 16 = 12 bits
// 1 = 16 bits

clang does not require -msse2 or -msse for inline, except
the "x" parameter. So change this to "m" for 32 bit. 64 bit
requires sse2 so use "x" for 64 bit.
gcc requires -msse for xmm registers in clobber list.
Reduce compiler requirement from -msse2 to -msse for enabling
assembly.

H010 is 10 bit planar format with 10 bits in lower bits.
P010 is 10 bit biplanar format with 10 bits in upper bits.
This function weaves the U and V channels and shifts the bits
into the upper bits.

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.

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.

YUV 411 is very uncommon format. Remove support.
Update documentation to reflect that 411 is deprecated.
Simplify tests for YUV to only test with the new side by side YUV but keep old 3 plane test around with a macro for now.

Work around for android full debug build runnign out of registers.
5 functions were running out of registers causing the compiler error
error: 'asm' operand has impossible constraints
These functions mostly have 4 pointers, a counter (width) and a tempory
eax register. With fpic and debug using stackframes, 2 registers are
unavailable. So a total of 8 registers are used.
Although fpic and stack frame dont apply to assembly, the compiler
reserves 2 registers. The optimized version builds, so its likely
freeing up the registers once it knows they are not used.
These functions used to build, so compile options and/or compiler may
have updated.. likely fpic was turned on.
An attribute can be done to disable each, and will avoid using the
2 GPR registers, but they are still reserved and unavailable in debug
builds on current compilers (gcc 4.9 and clang 3.8).

Inline that uses temporary variables is currently initializing them
to 0 and passing in as output "+r".
This CL replaces the output constraint to "=&r" for most meaning an
output with early write (before inputs). This allows the initialize
to zero step to be removed, saving 1 instruction.

previously the I411 format used movd to read U, V pixels.
But this reads 4 bytes, and can cause a memory exception.
pinsrw can be used, but fails on drmemory 1.5, and is slow.
So in this change a movzxw is used to read 2 bytes into EBX,
then copy to xmm0 with movd.
Slightly slower, but no memory exception

On Arm the YVU to RGB conversions move constants into registers.
This change does the same for 64 bit intel builds where additional
registers are available.
The AVX2 saves 3 instructions by because the 2nd argument needs to be a register, so a vmovdqu was avoided.
x64 builds using memory:
AVX2 I420ToARGB_Opt (3059 ms)
SSSE3 I420ToARGB_Opt (3959 ms)
Now using registers
