[ItaniumMangle] Mangle long double as __float128 for some Power targets GCC mangles long double like __float128 in order to support compatibility with ABI variants which had a different interpretation of long double. This fixes PR23791. llvm-svn: 239421

// RUN: %clang_cc1 -triple powerpc64-unknown-linux-gnu %s -emit-llvm -o - | FileCheck %s --check-prefix=POWER64-LINUX
// RUN: %clang_cc1 -triple powerpc-unknown-linux-gnu %s -emit-llvm -o - | FileCheck %s --check-prefix=POWER-LINUX
[SystemZ] Mangle long double as __float128 In r239421, the mangling of long double on PowerPC Linux targets was changed to use "g" instead of "e". This same change also needs to be done for SystemZ (all targets, since we support only Linux on SystemZ anyway). This is because an old ABI variant set "long double" to a 64-bit type equivalent to "double", and the "e" mangling code is still used to refer to that old ABI for compatibility reasons. llvm-svn: 239822
