Use llvm::endianness::{big,little,native} (NFC)
Note that llvm::support::endianness has been renamed to llvm::endianness while becoming an enum class. This patch replaces {big,little,native} with llvm::endianness::{big,little,native}. This patch completes the migration to llvm::endianness and llvm::endianness::{big,little,native}. I'll post a separate patch to remove the migration helpers in llvm/Support/Endian.h: using endianness = llvm::endianness; constexpr llvm::endianness big = llvm::endianness::big; constexpr llvm::endianness little = llvm::endianness::little; constexpr llvm::endianness native = llvm::endianness::native;
