Add intrinsics and missing LLVM AsmParser files for Windows ARM64

llvm::parseIR in llvm-7.0\llvm\lib\IRReader\IRReader.cpp calls parseAssembly
which is defined in lib/AsmParser/Parser.cpp, but the latter file is not
included in swiftshader_llvm which causes unresovled symbol for linking.
This CL added the necessary source files under llvm\AsmParser to
swiftshader_llvm.

This CL also changed __rdtsc() to use Windows ARM64 intrinsic _ReadStatusReg
to get cycle counter as alternative of __rdtsc().
