[PATCH v1 02/34] LoongArch: Set long double width to 128 in la32

[mengqinggang]

From: Jiajie Chen <c...@jia.je>

According to latest loongarch procedure call standard, sizeof(long
double) == 128 in ilp32 data model regardless of target bitness.

gcc/ChangeLog:

        * config/loongarch/loongarch.cc: Use TFmode for long double
        regardless of target bitness.
        * config/loongarch/loongarch.h: Set LONG_DOUBLE_TYPE_SIZE to 128
        regardless of target bitness.
