Description

[IR] Add Freeze instruction

Summary:

Define Instruction::Freeze, let it be UnaryOperator
Add support for freeze to LLLexer/LLParser/BitcodeReader/BitcodeWriter The format is %x = freeze <ty> %v
Add support for freeze instruction to llvm-c interface.
Add m_Freeze in PatternMatch.
Erase freeze when lowering IR to SelDag.
