From: Richard Henderson <richard.henderson@linaro.org>
We had two sets of variables: arg_start/arg_end, and
arg_strings/env_strings. In linuxload.c, we set the
first pair to the bounds of the argv strings, but in
elfload.c, we set the first pair to the bounds of the
argv pointers and the second pair to the bounds of
the argv strings.
Remove arg_start/arg_end, replacing them with the standard
argc/argv/envc/envp values. Retain arg_strings/env_strings
with the meaning we were using in elfload.c.

Commit 31330e6cecfd ("linux-user/s390x: Implement setup_sigtramp")
removed an unused field from rt_sigframe, disturbing offsets of other
fields and breaking unwinding from signal handlers (e.g. libgcc's
s390_fallback_frame() relies on this struct having a specific layout).
Restore the field and add a comment.

From: Ilya Leoshkevich <iii@linux.ibm.com>
clang-built s390x branch-relative-long test fails on clang-built s390x
QEMU due to the following sequence of events:
- The test zeroes out a code page, clang generates exrl+xc for this.
- do_helper_xc() is called. Clang generates exrl+xc there as well.
- Since there already exists a TB for the code in question, its page is
read-only and SIGSEGV is raised.
- host_signal_handler() calls host_signal_write() and the latter does
not recognize exrl as a write. Therefore page_unprotect() is not
called and the signal is forwarded to the test.
Fix by treating EXRL (and EX, just in case) as writes. There may be
false positives, but they will lead only to an extra page_unprotect()
call.
