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 0b0d3320db (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.

It is now declared for all tcg targets in tcg.h,
so the tcg target specific declarations are redundant.

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.
