Add a new kind of IR stmt: "instruction marks" (IRStmt_IMark), so as
to support profiling. It is the responsibility of front ends (toIR.c)
to generate these. For each instruction, the first IR stmt emitted
should be an IMark, stating the guest address and length of the guest
instruction represented by the IR that follows. All IR stmts
following the IMark but before the next IMark are then assumed to
'belong to' the guest insn described by the first IMark. IMarks do
not denote executable code and can be ignored at any point in the
proceedings; they are an optional addition which help
profiling-annotators to navigate the IR stmt stream.
This commit adds IR level infrastructure for IMarks and IMark
generation in the x86 front end. The amd64 and ppc32 front end are
not yet done.

Add guest_TISTART and guest_TILEN fields to all guest state structs,
since eventually users of the library will refer to them, and unless
they exist in all guest states, compilation failure will result.

invalidated by any icache-flushing instruction encountered. On x86
and amd64 there is no such insn and so they are zeroed at startup and
play no further role at all. But on ppc32 they are written to as a
result of executing an 'icbi' instruction.

A major overhaul of the way integer register decoding is done on
amd64.
The presence of REX bytes -- whilst apparently a simple change --
significantly complicates instruction decoding. The main problem is
that integer register numbers are now split into two pieces, one bit
from the REX byte and three bits from the modrm byte (or wherever).
The tricky bit is to always ensure that the correct pieces are
reassembled to form 4-bit register numbers. Prior to this commit, it
was easy to make that kind of error -- eg, conjoining the REX.B bit
with the 'g' modrm field to produce a nonsense register number. This
commit rearranges the handling functions for integer registers to make
that kind of error much less likely, basically by not allowing you to
deal in fragments of register fields unless absolutely necessary.

Re-arranged switchback::run_simulator a little, so can print translation of current bb (so if test breaks @ N, we can switchback @ N and N gets printed)

Fill in a huge number of amd64 floating point cases, and start to
reinstate the old x87 instruction decoder.

Fixed a backend shift bug: src/dst were swapped in emitted code.
Also fixed an assembly printf for Set32.

Cleaning up the x86 back end: get rid of instruction variants which
the instruction selector will never generate. I guess this
demonstrates that the majority of operations are sufficiently rare
that it is not worth going to much effort to generate good code for
them.
