Micro-manage clang to get the expected inlining for cpu_search().
Mark cpu_search_lowest/cpu_search_highest/cpu_search_both as noinline,
while cpu_search() gets always_inline.  With the attributes set,
cpu_search() is inlined in wrappers, and if()s with constant
conditionals are optimized.

On some tests on many-core machine, the hwpmc reported samples for
cpu_search*() are reduced from 25% total to 9%.
