613012246f Improve callgrind performance by 4 to 8% using UNLIKELY 
Performance improvements from 4 to 8% obtained on amd64 on the perf tests by:
1. using UNLIKELY inside tracing macros
2. avoid calling CLG_(switch_thread)(tid) on the hot patch setup_bbcc
   unless tid differs from CLG_(current_tid).

4c07b236f4 Add testcase to check the emulation warning for new supported opcodes 
on hosts without floating point extension facility.
See companion patch VEX r2501.
Part of fixing bugzilla #306098.

02be5e72db Change s390-features to allow testing for absence of a feature. 
This is infintely less painful than to find out how to invert
the condition in a test prerequisite.

a4d1060ccf vbit tester: Disable Iop_CmpLT64S and Iop_CmpLE64S for ppc because 
they cause assertion failures.
Do not test Iop_CmpORDxyz on ppc because the vbit tester does not 
support them. This is just so we don't have to add another .exp file for ppc.

0d0e6346db Add a tester for V-bit propagation through IROps. 
The tester is located in memcheck/tests/vbit-test.
It needs the following support on the valgrind / VEX side:
(1) a new client request VG_USERREQ__VEX_INIT_FOR_IRI
(2) a new "special instruction" on all architectures inserted via
    VALGRIND_VEX_INJECT_IR
(3) VEX changes to detect the special insn and insert IR (ir_inject.c)

The README file in vbit-test has some more information.
See also VEX r2490.  Fixes bugzilla #300102.

3abbddda09 fix 301281 valgrind hangs on OS X when the process calls system() 
After looking more in depth, gdbserver must not be terminated
in PRE(posix_spawn) on MacOS: this is running in the parent and
(on MacOS) is a single syscall similar to a fork+exec.
On linux, posix_spawn is implemented using 2 syscalls
(fork followed by exec).
