A few of our headers have some #include before the guard.

looking at the set of guests more closely shows that the 8-bit immediate
operand for the bic can only be satisfied with one guest in tree:
baseline m-profile -- 10-bit pages with aligned 4-byte memory ops.
Therefore it does not seem useful to keep this path.

accel: Remove unused AccelClass::opt_name attribute
The AccelType type was converted to AccelClass QOM
object on
b14a0b7469f, and the original data type had
a field to store the option name which in turn was
used to search an accelerator. The lookup method
(accel_find) changed too, making the option field
unnecessary but it became AccelClass::opt_name despite
that. Therefore, and given that none accelerator
implementation sets AccelClass::opt_name, let's

more consistent for both file and folder object types.

Finalize implementation of the "Vector Facility" for s390x TCG. Add it
to the QEMU CPU model, so it is enabled as default.
Also:
- One fix (and one workaround) for the STFLE instruction
- Fix the alignment of vector registers (and change the data type)
- Properly generate ELF_HWCAP for s390x for linux-user

s390x/tcg: Introduce tcg_s390_vector_exception()
Handling is similar to data exceptions, however we can always store the
VXC into the lowore and the FPC:
z14 PoP, 6-20, "Vector-Exception Code"
When a vector-processing exception causes a pro-
gram interruption, a vector-exception code (VXC) is
stored at location 147, and zeros are stored at loca-
tions 144-146. The VXC is also placed in the DXC
field of the floating-point-control (FPC) register if bit
45 of control register 0 is one. When bit 45 of control
register 0 is zero and bit 46 of control register 0 is
one, the DXC field of the FPC register and the con-
tents of storage at location 147 are unpredictable.

s390x/tcg: Store only the necessary amount of doublewords for STFLE
The PoP (z14, 7-382) says:
Doublewords to the right of the doubleword in which the
highest-numbered facility bit is assigned for a model
may or may not be stored.
However, stack protection in certain binaries can't deal with that.
"gzip" example code:
f1b4: a7 08 00 03 lhi %r0,3
f1b8: b2 b0 f0 a0 stfle 160(%r15)
f1bc: e3 20 f0 b2 00 90 llgc %r2,178(%r15)

f1cc: b9 14 00 22 lgfr %r2,%r2
f1d0: eb 11 00 20 00 0d sllg %r1,%r1,32
f1d6: b2 4f 00 11 ear %r1,%a1

f1ea: 07 fe br %r14
f1ec: c0 e5 ff ff 9d 6e brasl %r14,2cc8 <__stack_chk_fail@plt>
In QEMU, we currently have:
max_bytes = 24
the code asks for (3 + 1) doublewords == 32 bytes.
If we write 32 bytes instead of only 24, and return "2 + 1" doublewords
("one less than the number of doulewords needed to contain all of the
facility bits"), the example code detects a stack corruption.
In my opinion, the code is wrong. However, it seems to work fine on
real machines. So let's limit storing to the minimum of the requested
and the maximum doublewords.
