Subject: [mips] Partially revert r223927: Removing __SIZEOF_INT128__ macro for MIPS64
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1321cbe4e8528726908c38a94afbed4f5ccaa03d;p=clang

[mips] Partially revert r223927: Removing __SIZEOF_INT128__ macro for MIPS64

Partially revert r223927 because LLVM gained support for 128-bit integers
in r227089. Modify and keep the tests that verify the definition of the
macro __SIZEOF_INT128__ for MIPS64 BE & LE in the preprocessor.
