Commit 9b9a970a23
(target-lm32/microblaze: Typedef struct CPU{MB,LM32}State)
introduced necessary typedefs for cpu_mmu_index() and mmu.h
respectively.
On some GCC versions this leads to "error: redefinition of typedef".
Drop the original typedef to hopefully fix the build.

Move softmmu_exec.h include directives from target-*/exec.h to
target-*/op_helper.c. Move also various other stuff only used in
op_helper.c there.
Define global env in dyngen-exec.h.
For i386, move wrappers for segment and FPU helpers from user-exec.c
to op_helper.c. Implement raise_exception_err_env() to handle dynamic
CPUState. Move the function declarations to cpu.h since they can be
used outside of op_helper.c context.
LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and
env_to_regs().
ARM: make raise_exception() static.
Convert
#include "exec.h"
to
#include "cpu.h"
#include "dyngen-exec.h"

Function gen_pc_load was introduced in commit
d2856f1ad4.
The only reason for parameter searched_pc was
a debug statement in target-i386/translate.c.
Parameter puc was needed by target-sparc until
commit d7da2a1040.
Remove searched_pc from the debug statement and remove both
parameters from the parameter list of gen_pc_load.
As the function name gen_pc_load was also misleading,
it is now called restore_state_to_opc. This new name
was suggested by Peter Maydell, thanks.
v2: Remove last parameter, too, and rename the function.
v3: Fix [] typo in target-arm/translate.c.
Fix wrong SHA1 object name in commit message (copy+paste error).

float*_eq functions have a different semantics than other comparison
functions. Fix that by first renaming float*_quiet() into float*_eq_quiet().
Note that it is purely mechanical, and the behaviour should be unchanged.
That said it clearly highlight problems due to this different semantics,
they are fixed later in this patch series.

tcg_gen_exit_tb takes a parameter of type tcg_target_long,
so the type casts of pointer to long should be replaced by
type casts of pointer to tcg_target_long (suggested by Blue Swirl).
These changes are needed for build environments where
sizeof(long) != sizeof(void *), especially for w64.
