sim: sync build_warnings handling with gdb

The sim code gets the logic for SIM_AC_OPTION_WARNINGS from gdb, but
it hasn't been updated in a good long while.  Sync with the latest
gdb code.

There is a sim specific change in here: we disable -Werror for now.
This is because all sim code atm contains warnings.  Will probably
have to slowly add a white list of targets which can tolerate this
until everyone is updated.

SEGV during AX eval of OP_DOUBLE (unsupported)

To reproduce the problem, simply try the following with any program:

    (gdb) maintenance agent-eval 1.0
    Critical error handler: process [...] terminated due to access violation

(this is on Windows; on GNU/Linux, the libc copes better)

The problem is quite simple: gen_expr is given an expression that
contains an unrecognized operator (OP_DOUBLE in this case). When that
happens, it tries to report an error with a string image of the operator
in the error message.  Conversion of the opcode into a string is done
using op_string which, despite its name, probably is not what the author
was looking for.  This function returns NULL for a lot of the opcodes,
thus triggering the crash.

There is a function that corresponds to what we are looking for:
expprint.c:op_name. It was static, though, so I made it non-static,
and used it from ax-gdb.c:gen_expr.

gdb/ChangeLog:

        * expression.h (op_name): Add declaration.
        * expprint.c (op_name): Remove declaration.  Make non-static.
        * ax-gdb.c (gen_expr): Use op_name instead of op_string.

[Ada] Crash when trying to set value of packed array element

Consider the following declaration:

   type Small is new Integer range 0 .. 2 ** 4 - 1;
   type Simple_Array is array (1 .. 4) of Small;
   pragma Pack (Simple_Array);

   SA : Simple_Array := (1, 2, 3, 4);

Trying to change the value of one of the elements in the packed array
causes the debugger to crash:

    (gdb) set sa(3) := 9
    [1]    4880 segmentation fault  gdb -q foo

The circumstances leading to the crash are as follow:

   . ada_evaluate_subexp creates a value corresponding to "sa(3)".

   . ada_evaluate_subexp then tries to assign 9 to this value, and
     for this calls value_assign (via ada_value_assign).

   . Because the array is packed, the destination value is 3 bits long,
     and as a result, value_assign uses the parent to determine that
     element byte address and offset:

      | if (value_bitsize (toval))
      |   {
      |     struct value *parent = value_parent (toval);
      |
      |     changed_addr = value_address (parent) + value_offset (toval);

The destination value (corresponding to "sa(3)") was incorrectly created
by ada-lang.c:ada_value_primitive_packed_val, because the "parent" was
left as NULL. So, when we try to dereference it to get the parent address,
GDB crashed.

The first part of the fix therefore consists in setting that field.
This required the addition of a new "setter" in value.[hc].  It fixes
the crash, but is still not sufficient for the assignment to actually
work.

The second part of the problem came from the fact that value_assign
seems to expect the "child"'s address to be equal to the parent's address,
with the difference being the offset. Unfortunately, this requirement was
not followed by ada_value_primitive_packed_val, so the second part of
the fix consisted in fixing that.

Still, this was not sufficient, because it caused a regression when
trying to perform an aggregate assignment of a packed array of packed
record.  The key element here is the nesting of packed entities.
Looking at the way ada_value_primitive_packed_val creates the value
of each sub-component, one can see that the value's offset is set
to the offset compared to the start of the parent. This was meant to
match what value_primitive_field does as well.

So, with our array of records, if the record offset was 2, and if
the field we're interested in that record is at offset 1, the record
value's offset would be set to 2, and the field value's offset would
be set to 1. But the address for both values would be left to the
array's address. This is where things start breaking down, because
the value_address function for our field value would return the
address of the array + 1, instead of + 3.

This is what causes the final issue, here, because ada-lang.c's
value_assign_to_component needs to compute the offset of the
subcomponent compared to the top-level aggregate's start address
(the array in our case). And it does so by subtracting the array's
address from the sub-component's address.  When you have two levels
of packed components, and the mid-level component is at an offset of
the top-level component, things didn't work, because the component's
address was miscomputed (the parent's offset is missing).

The fix consists is fixing value_address to match the work done by
value_primitive_field (where we ignore the parent's offset).

Problem after hitting breakpoint on Windows (with GDBserver)

When debugging on Windows with GDBserver, the debugger starts
failing after hitting a breakpoint.  For instance:

    (gdb) b foo
    Breakpoint 1 at 0x40177e: file foo.adb, line 5.
    (gdb) cont
    Continuing.

    Breakpoint 1, foo () at foo.adb:5
    5          Put_Line ("Hello World.");  -- STOP
    (gdb) n

    Program received signal SIGSEGV, Segmentation fault.
    0x00401782 in foo () at foo.adb:5
    5          Put_Line ("Hello World.");  -- STOP

There are two issues:

  1. While trying to re-insert a breakpoint that is still inserted
     in memory, insert_bp_location wipes out the breakpoint location's
     shadow_contents.  As a consequence, we cannot restore the proper
     instruction when removing the breakpoint anymore.  That's why
     the inferior's behavior changes when trying to resume after
     the breakpoint was hit.

  2. mem-break.c:default_memory_insert_breakpoint passes a breakpoint
     location's shadow_contents as the buffer for a memory read.
     This reveals a limitation of the various memory-read target
     functions.  This patch documents this limitation and adjust
     the two calls that seem to hit that limitation.

gdb/ChangeLog:

        * breakpoint.c (breakpoint_xfer_memory): Add assertion.
        Update function description.
        (insert_bp_location): Do not wipe bl->target_info out.
        * mem-break.c: #include "gdb_string.h".
        (default_memory_insert_breakpoint): Do not call target_read_memory
        with a pointer to the breakpoint's shadow_contents buffer.  Use
        a local buffer instead.
        * m32r-tdep.c (m32r_memory_insert_breakpoint): Ditto.
