[Bug target/29983] New: [Regression 4.2] Out of range offset for ldrd/strd intruction.

GCC 4.2 is generating wrong offset while compiling the attached example. This
only happens when using -mcpu=iwmmxt option. It works ok on 3.4.6

/tmp/cc4oD6OO.s: Assembler messages:
/tmp/cc4oD6OO.s:15151: Error: bad immediate value for half-word offset (328)
/tmp/cc4oD6OO.s:15151: Error: bad immediate value for half-word offset (512)
/tmp/cc4oD6OO.s:15151: Error: bad immediate value for half-word offset (328)
/tmp/cc4oD6OO.s:15151: Error: bad immediate value for half-word offset (328)

To reproduce this compile the testcase with gcc -O2 -c -mcpu=iwmmxt
