* Pass host CPU features to LLVM target
This gets `test_gemm_fp16` to pass on Windows. It would fail because the
generated machine code would call compiler-rt functions to to perform
truncating. This gets the test to pass on some hardware, because LLVM
gets access to more instructions. Essentially this is similar to
`-march=native`.
Unless this was intentionally left as is to be re-implemented fully in
LLVM IR or something.

* more conditions for shift rewrite mul/idiv
* make ptx test uint so the new condition is true
* delete idiv test
* rewrite to 0 is wrong for idiv, as denominator is cast to 0 before division
* mul/div by 2**(large count) is unsupported anyway
Number after .so is abi version, it is always 1 for libgcc_s.
Most linux systems set default library versions via symlinks that are
simply followed to get actual elf, however conda does it via linker
scripts which ctypes doesn't follow (below contents of libgcc_s.so):
```
/* GNU ld script
Use the shared library, but some functions are only in
the static library. */
GROUP ( libgcc_s.so.1 -lgcc )
```
ctypes.util.find_library thinks that this is the actual elf and
ctypes.CDLL just loads this text file as a shared library. The result
is:
```
File "/home/me/src/tinygrad/tinygrad/device.py", line 223, in CPUProgram
helper_handle = ctypes.CDLL(ctypes.util.find_library('System' if OSX else 'gcc_s'))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/home/me/miniforge3/envs/tinygrad/lib/python3.12/ctypes/__init__.py", line 379, in __init__
self._handle = _dlopen(self._name, mode)
^^^^^^^^^^^^^^^^^^^^^^^^^
OSError: /home/me/miniforge3/envs/tinygrad/lib/libgcc_s.so: invalid ELF header
```
