Knowing the value of %asi at translation time means that we
can handle the common settings without a function call.
The steady state appears to be %asi == ASI_P, so that sparcv9
code can use offset forms of lda/sta. The %asi register gets
pushed and popped on entry to certain functions, but it rarely
takes on values other than ASI_P or ASI_AIUP. Therefore we're
unlikely to be expanding the set of TBs created.

Doing this instead of saving the raw PS_PRIV and TL. This means
that all nucleus mode TBs (TL > 0) can be shared. This fixes a
bug in that we didn't include HS_PRIV in the TB flags, and so could
produce incorrect TB matches for hypervisor state.
The LSU and DMMU states were unused by the translator. Including
them in TB flags meant unnecessary mismatches from tb_find_fast.

disas/arm-a64.cc is careful to include only the bare minimum that
it needs---qemu/osdep.h and disas/bfd.h. Unfortunately, disas/bfd.h
then includes qemu-common.h, which brings in qemu/option.h and from
there we get the kitchen sink.
This causes problems because for example QEMU's atomic macros
conflict with C++ atomic types. But really all that bfd.h needs
is the fprintf_function typedef, so replace the inclusion of
qemu-common.h with qemu/fprintf-fn.h.

The conventional way to ensure a header can be included multiple times
is to bracket it like this:
#ifndef HEADER_NAME_H
#define HEADER_NAME_H
...
#endif
where HEADER_NAME_H is a symbol unique to this header.
The endif may be optionally decorated like this:
#endif /* HEADER_NAME_H */
Unconventional ways present in our code:
* Identifiers reserved for any use:
#define _FILEOP_H
* Lowercase (bad idea for object-like macros):
#define __linux_video_vga_h__
* Roundabout ways to say the same thing (and hide from grep):
#if !defined(__PPC_MAC_H__)
#endif /* !defined(__PPC_MAC_H__) */
* Redundant values:
#define HW_ALPHA_H 1
* Funny redundant values:
# define PXA_H "pxa.h"
* Decorations with bangs:
#endif /* !QEMU_ARM_GIC_INTERNAL_H */
The negation actually makes sense, but almost all our header guard
#endif decorations don't negate.
* Useless decorations:
#endif /* audio.h */
Header guards are not the place to show off creativity. This script
normalizes them to the conventional way, and cleans up whitespace
while there. It warns when it renames guard symbols, and explains how
to find occurences of these symbols that may have to be updated
manually.
Another issue is use of the same guard symbol in multiple headers.
That's okay only for headers that cannot be used together, such as the
*-user/*/target_syscall.h. This script can't tell, so it warns when
it sees a reuse.
The script also warns when preprocessing a header with its guard
symbol defined produces anything but whitespace.
The next commits will put the script to use.
