This patch further reduces the memory used by TT/TC (by about 15Mb
on 32 bits memcheck default nr of sectors).
Memory is reduced by using UShort typedef-s for Sector no and TTE no.
Note that for TTE no, we had a mixture of UShort, UInt and Int used
depending on the place (a TTE no was in any case constrained to be an UShort).
The bss memory/startup space is also reduced by allocating the htt on demand
(like tt and tc), using mmap the first time a sector is initialised.
Changes:
* pub_core_transtab.h :
* 2 typedef to identify a sector and a tt entry (these 2 types are UShort)
* add 2 #define 'invalid values' for these types
* change the interface to use these types rather than UInt
* m_transtab.c
* use wherever relevant these 2 new types rather than UInt or UShort
* replace the use of -1 by INV_SNO or INV_TTE
* remove now useless typecast from Int/UInt to UShort for tte
* schedule.c: use the new types

Entangle header files a bit. Specifically, pub_core_basics.h no longer
includes libvex.h. It isn't needed to successfully compile pub_core_basics.h
standalone and the declarations libvex.h provides aren't used as broadly as
the comment in the code implied.
Move the guest-specific includes and some ifdeffery to the new file
pub_core_guest.h
For the curious reader: The change above avoids a problem when linking the
linux-launcher which previously included libvex.h indirectly. libvex.h also
defines the inline function LibVEX_Alloc which, when emitted, causes the
link step to fail due to unresoled references (as the launcher does not link
against libvex.a). See also BZ #339542.

Allow the user to dimension the translation cache
A previous commit had decreased to 6 (on android) and increased to 16
(other platforms) the nr of sectors in the translation cache.
This patch adds a command line option to let the user specify
the nr of sectors as e.g. 16 sectors might be a lot and cause
an out of memory for some workloads or might be too small for
huge executable or executables using a lot of shared libs.

Improvements to the built-in profiling infrastructure:
--profile-flags=00000000 now prints summary statistics, one line per
profiled block, but with no translation details. Previously it had
no effect.
--profile-interval=<number> is a new flag that causes the profile data
to be dumped and zeroed every <number> event checks. This makes it
possible to get profile data without waiting for runs to end, and to
get profile data which depends on the current workload etc. If
--profile-interval=0 or is unset, the profile is printed only once, at
the end of the run, as before.
--profile-flags=XXXXXXXX (for at least one nonzero X) prints the
summary lines both at the start and end of the profile, so you don't
have to scroll back up to the top to see the summary.

For --profile-flags=, weight the counts by the number of guest insns
in each IRSB, rather than considering each IRSB to have a weight of 1.
This probably gives more representative profiles, especially post
t-chain merge, which made inter-SB transitions more or less free
compared to what they were before.

Redo the dispatcher's fast-cache mechanism (VG_(tt_fast) et al) to be
more cache friendly. This changes the mechanism from being a table of
pointers to (guest address, translated code pairs) to being a table of
pairs (guest address, pointer to translated code). The effect ranges
from zero up to about 20% performance improvement on memcheck, the
biggest effects being seen for programs which jump around a large
number of blocks of code and whose data set does not fit in L2.

This commit merges in changes from branches/ASPACEM (specifically,
changes from r4341 through r4787 inclusive). That branch is now dead.
Please do not commit anything else to it.
For the most part the merge was not troublesome. The main areas of
uncertainty are:
- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
and include it in a couple of places. Building etc seems to still
work, but I haven't tried building the documentation.
- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
stuff was moved from -generic to -linux after the branch was created.
I think that is satisfactorily glued back together now.
- Regtests: although this appears to work, no .out files appear, which
is strange, and makes it hard to diagnose regtest failures. In
particular memcheck/tests/x86/scalar.stderr.exp remains in a
conflicted state.
- amd64 is broken (slightly), and ppc32 will be unbuildable. I'll
attend to the former shortly.

Support for self modifying code on unfriendly platforms (x86, amd64)
via the use of self-checking translations. (Friendly platforms which
have icache-invalidation instructions we can observe, such as ppc32,
are already handled correctly.) This should finally fix the
longstanding problem of V incorrectly handling calls of statically
nested functions (a gcc extension), and more generally make it a lot
easier to use V to debug dynamic code generation systems.
Since self-checking is a large performance overhead, there is some
control via a command line flag:
--smc-support=none
Don't make any translations self-checking.
--smc-support=stack
Add checking code for translations taken from segments which
have the SF_GROWDOWN flag set -- stacks, basically.
This is the default. It should make gcc nested functions and
GNU Ada work correctly with no intervention from the user.
--smc-support=all
Make all translations self-checking. This is expensive and
you want to do this if you're debugging a JIT compiler or
some such.
