The patch is based on D144994.

D151030 added the module definitions for the module std.
This patch wires in the module and enables the basic testing.

Some notable features are missing:
- There is no test that libc++ can be fully imported as a module.
- This lacks the parts for the std.compat module.
- The module is not shipped with libc++.

Implements parts of
- P2465R3 Standard Library Modules std and std.compat

[InstCombine][CGP] Move swapMayExposeCSEOpportunities() fold

InstCombine tries to swap compare operands to match sub instructions
in order to expose "CSE opportunities". However, it doesn't really
make sense to perform this transform in the middle-end, as we cannot
actually CSE the instructions there.

The backend already performs this fold in
https://github.com/llvm/llvm-project/blob/18f5446a45da5a61dbfb1b7667d27fb441ac62db/llvm/lib/CodeGen/SelectionDAG/TargetLowering.cpp#L4236
on the SDAG level, however this only works within a single basic block.

To handle cross-BB cases, we do need to handle this in the IR layer.
This patch moves the fold from InstCombine to CGP in the backend,
while keeping the same (somewhat dubious) heuristic.

[libc] Move the definitions of the standard IO streams to the platform

This patch moves the definitions of the standard IO streams to the
platform file definition. This is necessary because previously we had a
level of indirection where the stream's `FILE *` was initialized based
on the pointer to the internal `__llvm_libc` version. This cannot be
resolved ahead of time by the linker because the address will not be
known until runtime. This caused the previous implementation to emit a
global constructor to initialize the pointer to the actual `FILE *`. By
moving these definitions so that we can bind their address to the
original file type we can avoid this global constructor.

This file keeps the entrypoints, but makes them empty files only
containing an external reference. This is so they still appear as
entrypoints and get emitted as declarations in the generated headers.
