Fix leak scan SEGV catcher when ptr starts in unreadable page (readable for aspacemgr)
The fault catcher installed during leak scan to catter e.g. for
possible desynchronisation between real protection and aspacemgr
was not activated when the scanned ptr was directly pointing in
a desynchronised page.
This was (initially only) visible on ppc32 (gcc110) as the page size of
gcc110 is big (64 K).
=> modified the leak-segv-jmp test so as to produce the problem also
on systems with smaller pages.
The fix consists in calling the setjmp before the scan loop,
and skip the bad address which has been recorded by the fault
catcher.
Also, deemed better to just skip one single Addr rather than a full page
(e.g. to skip less data in case some addresses are unreadable e.g.
on strange hardware).
Performance of the leak scan has been measured, seems slightly
faster on x86,amd64 and ppc32. Slightly slower on ppc64.
Also if verbose argument is given, outputs the nr of bytes skipped
due to fault.

Fix compilation problem of memcheck/tests/leak-segv-jmp on ppc32
With the change, the test compiles on ppc32.
However, the test fails miserably with
Segmentation fault
while the whole purpose of the test was to see the leak search
would *not* segfault.
More investigations needed, but still committing as is to let
the tests compile and run.

mips64: Add a test case for mips64.
Add a function in the memcheck/tests/leak-segv-jmp.c for MIPS64
that execute the syscall. Because we added the mips64 case we
need to change the line number in *.exp file.
Fixes memcheck/tests/leak-segv-jmp for MIPS64.

Unbreak build on Mac_OS where __NR_mprotect is not defined.
The test is not executed on Darwin but should compile.
(based on fix suggestion by Rich Coe)

Add a test which checks the leak search recovery mechanism
The leak search must recover if unreadable pages are scanned.
This test creates such unreadable pages by doing non SIMD mprotect
syscall (not seen by the aspacemgr).
