remove unnecessary setFloatMode calls 
Now that Strict is the default, these calls only add noise.

c7804277bf @floatToInt now has safety-checked undefined behavior 
when the integer part does not fit in the destination integer type

 * Also fix incorrect safety triggered for integer casting an
   `i32` to a `u7`. closes #1138
 * adds compiler-rt function: `__floatuntidf`

dc8bda7e02 Add arbitrary-precision integer to std 
A few notes on the implementation:

 - Any unsigned power of two integer type less than 64 bits in size is supported
 as a Limb type.
 - The algorithms used are kept simple for the moment. More complicated
 algorithms are generally only more useful as integer sizes increase a
 lot and I don't expect our current usage to be used for this purpose
 just yet.
 - All branches (practically) have been covered by tests.

See 986a2b3243/bench
for rough performance comparison numbers.

Closes #364.

fcbb7426fa use * for pointer type instead of & 
See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'
