[RS6000] Don't put large integer constants in TOC for -mcmodel=medium

For -mcmodel=medium we can use toc-relative addressing to access
constants placed in read-only data, which is better since they can be
merged when in .rodata.cst8.

* config/rs6000/linux64.h (ASM_OUTPUT_SPECIAL_POOL_ENTRY_P): Exclude
integer constants when -mcmodel=medium.
