x86: add and use *_BIT constants for CR0, CR4, EFLAGS

The "BIT" macro cannot be used in top-level assembly statements
(it can be used in functions through the "i" constraint), because
old binutils such as the one in CentOS 7 do not support the "1UL"
syntax for numerals.

To avoid having to hard-code EFLAGS.AC being bit 18, define the constants
for CR0, CR4 and EFLAGS bits in terms of new macros for just the bit
number.
