Fix harmless if statements with empty body, spotted by clang

These clang errors are harmless but worth fixing:
CC ppc-softmmu/usb-ohci.o
/src/qemu/hw/usb-ohci.c:1104:59: error: if statement has empty body [-Wempty-body]
ohci->ctrl_head, ohci->ctrl_cur);...

target-sparc: Free instruction temporaries.

Rather than creating new temporaries for constants, use the
ones created in disas_sparc_insn. Remember the temps created
there so that they can be freed at the end of the function.

Profile data collected by TCG while booting sparc-test kernel:...

Sparc: fix exceptions in delay slot

Fix a case where an exception happens with the
instruction in the delay slot.

Recovery of branch condition in the exception handling
code was not converted to TCG. Because the condition
was bogus, wrong NPC could be selected from the two...

Large page TLB flush

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...

Move TARGET_PHYS_ADDR_SPACE_BITS to target-*/cpu.h.

Removes a set of ifdefs from exec.c.

Introduce TARGET_VIRT_ADDR_SPACE_BITS for all targets other
than Alpha. This will be used for page_find_alloc, which is
supposed to be using virtual addresses in the first place....
