[PATCH] D31573: [Builtins] Add IEEE 754 support for __fixunsxfti

[Weiming Zhao via Phabricator via llvm-commits]

weimingz updated this revision to Diff 93967.
weimingz added a comment.

these tests are the only 4 tests that use 128 bit long long.
Other tests that uses HAS_80_BIT_LONG_DOUBLE should be replaced with `__LDBL_MANT_DIG__ == 64`
