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.
