Some Tests in gcc.dg/graphite/ are failing for AVR target

[K_s, Vishnu]

Hi all,

Some of the tests added in gcc.dg/graphite are failing for AVR target, Because
size of the arrays defined are 'too' large for AVR. I'm wondering is it
possible to reduce the size of the array's in tests.

One example is gcc.dg/graphite/scop-0.c, which is failing with error 
"size of array 'a' is too large" when compiling with avr-gcc. 

Following tests are also failing for avr-gcc with error "size of array used
is too large".

gcc.dg/graphite/scop-22.c
gcc.dg/graphite/scop-3.c
gcc.dg/graphite/scop-dsyr2k.c
gcc.dg/graphite/scop-dsyrk.c
gcc.dg/graphite/scop-mvt.c
gcc.dg/graphite/scop-sor.c
gcc.dg/graphite/pr46185.c
