[lldb] Let LLDB depend on intrinsics_gen to fix non-deterministic module build failures Summary: When building with modules we currently fail randomly to build LLDB's modules and get error messages like below: ``` In file included from <module-includes>:1: In file included from llvm-project/llvm/include/llvm/IR/Argument.h:18: llvm-project/llvm/include/llvm/IR/Attributes.h:74:14: fatal error: 'llvm/IR/Attributes.inc' file not found #include "llvm/IR/Attributes.inc" ^~~~~~~~~~~~~~~~~~~~~~~~ ... In file included from llvm-project/lldb/source/Plugins/ABI/SysV-arm/ABISysV_arm.cpp:9: llvm-project/lldb/source/Plugins/ABI/SysV-arm/ABISysV_arm.h:12:10: fatal error: could not build module 'lldb_Wrapper' ``` The reason for this is that our source files can include Clang headers which in turn include files like Attributes.inc which are generated by intrinsics_gen. However, it seems Clang can't express this dependency in its CMake code, so intrinsics_gen is actually not guaranteed to be built before we start parsing LLDB source files and Clang headers. Clang worked around this by letting all libraries depend on intrinsics_gen, which at least lets their builds pass. As I haven't figured out how to solve these dependencies properly and I want to get the LLDB+Modules build green, I suggest we copy Clang's hack until we figure out how to get Clang's dependencies right.

# We need the headers generated by instrinsics_gen before we can compile
