[PATCH, AArch64] Handle SYMBOL_SMALL_TPREL appropriately

[Hurugalawadi, Naveen]

Hi,

Please find attached the patch that handles the operations on
SYMBOL_SMALL_TPREL appropriately.
It fixes gcc.dg/tls/opt-11.c regression on ilp32.

Please review the patch and let us know if its okay?
Regression tested on aarch64-elf.

Thanks,
Naveen
