x86/percpu: Rewrite x86_this_cpu_test_bit() and friends as macros

Rewrite the whole family of x86_this_cpu_test_bit() functions
as macros, so standard __my_cpu_var() and raw_cpu_read() macros
can be used on percpu variables. This approach considerably
simplifies implementation of functions and also introduces
standard checks on accessed percpu variables.

No functional changes intended.
