`where(self, 0)` incorrectly upcasted the output. `where(self, False)` is correct but looks unnatural, so added a cast at the end. Pattern matcher can fold the cast into where branches
* failed test case for getitem with leading Nones
torch matched numpy so tinygrad is incorrect.
another repro
```
t = np.arange(12).reshape((3, 4))
print(t[None, None, np.array([1, 2])])
t = torch.arange(12).reshape((3, 4))
print(t[None, None, torch.tensor([1, 2])].numpy())
t = Tensor.arange(12).reshape(3, 4)
print(t[None, None, Tensor([1, 2])].numpy())
```
* # noqa
default [low, high] changed from [-1.5, 1.5] to [-2, 2] (except tan).
dropped several explicit atol if it's unnecessarily larger than default 1e-6.
tested on mac, tinybox red / green
moved Sign logic to function.py, and backward always returns 0 to match torch.
rewrite abs as `self * self.sign()`, so it's backward also matches torch.

* It works?
* Clamp correctly
* Refactor
* Make code better
* Undo some stuff
* First step to trying to make floats work
* Floats work in Python op but not metal because int div is different
Python integerdivision was implemented as // which rounds towards
negative infinity, but C integer division rounds towards 0 so there
is an off-by-1 division error
* arange does cumsum with ints and then multiplies by step
This is so loop optimization can remain int only
* Undo a lot of symbolic changes
* Final check
* Cleanup
* There can be multiple phis
* Fix multiple phi op removal
* const sets dtype correctly
* Fix bugs
* Fix a couple bugs and add loop vars to resolve
* missed one

* actually emulate tensor cores
* fix test
* new style
run on TORCH since it's the fastest one on CI.
caught a bug in multinomial, and update the behavior of fancy index and gather to move the indices Tensor to same device as self.
fix when correction is too big. it seems to only work when input size is 0 though.
torch can output -inf in var when correction is too big, which does not make sense.
* fix Tensor.mean to compute the mean correctly with 0-length axes are selected
* add a regression test
* rename sum variable to sum_t to avoid conflict with built it function
* refactor Tensor.mean to has less lines
