Inconsistent forwarding about patmos

Fixed it locally, will push soon.. (it's in the read_GPR_EX function in
instructions.h).

The test case vliw_test/add (and possibly other test cases) show
inconsistent forwarding in the simulator. In the first cycle, r1 is
assigned 2 in pipeline 0 and 5 in pipeline 1. r2-r7 are assigned r1+r1
in the subsequent cycles. The result is that r1=5 (result from pipeline
1), r2=r3=4 (apparently forwarded from pipeline 0), and r4=r5=r6=r7=10
(forwarded from pipeline 1 or the register file). This should be fixed
such that the value in the register and the forwarded values are consistent.

Pushed it, r2-r7 = 10 now in the vliw add.s test.
