Step two in the transition, adding the new ldst opcodes.  Keep the old
opcodes around until all backends support the new opcodes.

There are several hosts with only a "div" insn.  Remainder is computed
manually from the quotient and inputs.  We can do this generically.

Commit 0b0d3320 (TCG: Final globals
clean-up) moved code_gen_prologue but forgot to update ppc code.
This broke the build on 32-bit ppc. ppc64 is unaffected.

GUEST_BASE support is now supported by all TCG backends, and is
now mandatory. Drop the now-pointless TCG_TARGET_HAS_GUEST_BASE
define (set by every backend) and the error if it is unset.

Targets may use a non standard definition of tcg_tb_exec
by defining this macro in their tcg_target.h.

This is used here by ppc. It will be used by the TCG interpreter, too.

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.
