[PATCH] Fix PR 37185, transpose-3.c fails in verify_stmts

[Razya Ladelsky <RAZYA at il dot ibm dot com>]

Hi,

This patch fixes the matrix testsuite fauilure that was reported in 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37185.
the problem was that after assigning the second operand 
for the statement, it was not updated.
All matrix reorg tescases pass on x86-64. Will check on power as well.

O.K for mainline?

Thanks,
Razya

ChangeLog:

        * matrix-reorg.c ( transform_access_sites): Update the stmt that 
was changed.
