re PR target/817 (ARM compiler generates out-of-range accesses to constant pool data) 

PR target/817
* arm.md (arm_movdi): Adjust neg_pool_range attribute to allow
for the fact that the pool entry uses two words.
(movdf_hard_insn): Similarly.  Also, ADR instruction can span
1k bytes.
(movdf_soft_insn): Similarly.
(movxf_hard_insn): Adjust neg_pool_range attribute to allow
for the fact that the pool entry uses three words.
