Sample code to reproduce the error

Running user code that uses a 32-bit Goto BLAS library through memcheck (from the valgrind 3.5.0 release or earlier releases) does issue a

vex x86->IR: unhandled instruction bytes: 0xF 0xE 0x89 0xE6

A sample code using the critical DTRSM BLAS function is attached. Get Goto BLAS
at http://www-prc.tacc.utexas.edu/resources/software/software.php?#blas, unpack,
compile it on a 32-bit Linux machine using ./quickbuild.32bit. Then, compile the
sample code, link it against Goto BLAS and run valgrind against it:

  gfortran -g sample.f90 -lgoto
  valgrind ./a.out

valgrind will bail out with above mentioned message.

This error is related to http://bugs.kde.org/show_bug.cgi?id=124499 in that this one occurs on x86 while #124499 occurred on x86_64. (It has been reported to the mailing list today.)

I'll provide a patch along with the first comment because there is only one file upload per comment allowed.
