tcg: Always define all of the TCGOpcode enum members.
By always defining these symbols, we can eliminate a lot of ifdefs. To allow this to be checked reliably, the semantics of the TCG_TARGET_HAS_* macros must be changed from def/undef to true/false. This allows even more ifdefs to be removed, converting them into C if statements. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
