The previous patch removed the need for parameter puc.
Is is now unused, so remove it.

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).

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.

All implementations are now the same, and there is only one caller,
so inline the function there.

QEMU uses a fixed page size for the CPU TLB. If the guest uses large
pages then we effectively split these into multiple smaller pages, and
populate the corresponding TLB entries on demand.
When the guest invalidates the TLB by virtual address we must invalidate
all entries covered by the large page. However the address used to
invalidate the entry may not be present in the QEMU TLB, so we do not
know which regions to clear.
Implementing a full vaiable size TLB is hard and slow, so just keep a
simple address/mask pair to record which addresses may have been mapped by
large pages. If the guest invalidates this region then flush the
whole TLB.

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
