Changes since v4:
* Simplified alignment checks by using tcg_gen_qemu_ld_i64 and
MO_ALIGN*.
Pavel Zbitskiy (3):
target/s390x: use regular spaces in translate.c
target/s390x: exception on non-aligned LPSW(E)
target/s390x: implement CVB, CVBY and CVBG
target/s390x/helper.h | 1
Both LPSW and LPSWE should raise a specification exception when their
operand is not doubleword aligned.

Changes since v3:
* Patches 1-6 were accepted, thanks!
* Use in1_la2 in op_cvb().
* Free a temp in op_cvb().
* Make ra const in helper_cvb().
* Use wrap_address() in helper_cvb().
* Add a minor formatting patch.
* Add LPSW(E) alignment check.

loop condition should be > and not >=.
If len_src is 1, then we should flip the 1st byte and pack the 2nd.
Since len_src is already decremented before the loop, the first
condition should be >=, and not >.

Suppose psw.mask=0x8000, cc=2, r1=0 and we do "ipm 1".
This command must touch only bits 32-39, so the expected output
is r1=0x2000. However, currently qemu yields r1=0x20008000,
because irrelevant parts of PSW leak into r1 during program mask
transfer.
