Convert all targets simultaneously, as the gen_intermediate_code
function disappears from the target. While there are possible
workarounds, they're larger than simply performing the conversion.

TB compile flags, tb_page_addr_t type, tb_cflags() and few
other methods are defined in "exec/translation-block.h".
All these files don't include "exec/translation-block.h" but
include "exec/exec-all.h" which include it. Explicitly include
"exec/translation-block.h" to be able to remove it from

Most targets define their restore_state_to_opc() handler in cpu.c.
In order to keep SPARC aligned, move sparc_restore_state_to_opc()
from translate.c to cpu.c.

[PMD: Move definitions to new target/sparc/translate.h]
In the helper functions flcmps and flcmpd we use a scratch float_status
so that we don't change the CPU state if the comparison raises any
floating point exception flags. Instead of zero-initializing this
scratch float_status, initialize it as a copy of env->fp_status. This
avoids the need to explicitly initialize settings like the NaN
propagation rule or others we might add to softfloat in future.
To do this we need to pass the CPU env pointer in to the helper.
