It is now declared for all tcg targets in tcg.h,

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.

Add an bswap16 and bswap32 ops, either using the rev and rev16
instructions on ARMv6+ or shifts and logical operations on previous
ARM versions. In both cases the result use less instructions than
the pure TCG version.

These ops are also needed by the qemu_ld/st functions.

Add an ext16u op, either using the uxth instruction on ARMv6+ or two
shifts on previous ARM versions. In both cases the result use the same
number or less instructions than the pure TCG version.

Also move all sign extension code to separate functions, so that they
can be reused in other parts of the code.

Instead of writing very compact code, declare all registers that are
clobbered or reserved one by one. This makes the code easier to read.

Also declare all the 16 registers to TCG, and mark pc as reserved.

Some targets like ARM would benefit to use 32-bit helpers for
div/rem/divu/remu.

Create a #define for div2 so that targets can select between
div, div2 and helper implementation. Use the helper version if none
of the #define are present.
