be1682ca4d 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.

23d716110b 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.

These fields contain the size and length of an area of icache
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.

f7a3fb1d87 Add %EBP/%RBP to the set of registers for which redundant-PUT 
elimination is not done.  This is needed so that Valgrind can
construct correct stack traces on x86/amd64.  Curiously enough old
UCode valgrind didn't do this correctly, but because it doesn't
optimise as aggressively as Vex, we didn't notice this.  Overall
result is that Vex-based valgrind now produces more accurate stack
traces, at least on x86, than valgrind-2.4.X will.
