- fpus and fpud are swaped.
- quarkse_em doesn't include FPX extensions.
- auto guessed opcode mechanism may ignore the option passed via -M<feature> option.

With the previous change, value.location.address is only valid for
lval_memory. This patch restrict some checking on value.lval on
using address. Since we have a check on VALUE_VAL in
set_value_address, we need to set VALUE_VAL properly before
set_value_address too.

value.regnum and value.next_frame_id are only used for lval_register,
so this patch moves them to union value.location. As a result, when
we copy value, only copy location, don't need to copy regnum and
next_frame_id.
This patch also changes regnum's type to int as there is no space
constraint, so update deprecated_value_regnum_hack return type too.

Nowadays, we set computed value's frame id, which is a misuse to me.
The computed value itself doesn't care about frame id, but function
value_computed_funcs (val)->read (or read_pieced_value) cares about
which frame the register is relative to, so 'struct piece_closure' is
a better place to fit frame id.
This patch adds a frame id in 'struct piece_closure', and use it
instead of using computed value's frame id.

Constify the data path between ui_out_wrap_hint and the wrap_indent
global, because we can. It's clearer that the argument passed to
wrap_hint is not intended to be modified by the ui_out implementation.

The wrapper uo_redirect seems like it should return the return value
from of implementation function, since callers rely on it, but it
doesn't.

It's not actually used, and removing it simplifies the upcoming patches
a bit. After the whole series, destroying an ui_out object will be
simply "delete uiout", which will call the default destructor.

* ui-out.h (ui_out_destroy): Remove.
Just a little cleanup, so the name is more consistent with the naming of
the equivalent structures of cli and tui. It goes away in subsequent
patches anyway, but it might help follow the changes in those patches...

This patch fixes two problems in the SPARC assembler:
- The diagnostic message
Error: Illegal operands: Immediate value in cbcond is out of range.
is incorrectly issued for non-CBCOND instructions that feature a
simm5 immediate field, such as MPMUL, MONTMUL, etc.
- When an invalid immediate operand is used in a CBCOND
instruction, two redundant error messages are issued to the
user, the second due to a stale fixup (this happens since
commit 85024cd8bc).
Some diagnostic tests for the CBCOND instructions are also
included in the patch.
Tested in both sparc64-linux-gnu and sparcv9-linux-gnu targets.

The function copy_bitwise used for copying DWARF pieces can potentially
be invoked for large chunks of data. For instance, consider a large
struct one of whose members is currently located in a register. In this
case copy_bitwise would still copy the data bitwise in a loop, which is
much slower than necessary.
This change uses memcpy for the large part instead, if possible.
gdb/ChangeLog:
* dwarf2loc.c (copy_bitwise): Use memcpy for the middle part, if
it is byte-aligned.
This adds a unit test for the copy_bitwise function in dwarf2loc.c.
With the old (broken) version of copy_bitwise this test would generate
the following failure message:
(gdb) maintenance selftest
Self test failed: copy_bitwise 11000000 != 10000000 (7+2 -> 0)
