The modulo operation computed rem(b+rem(a,b), b) which produces -1
for a=1 and b=2.
Switch to a - b * trunc(a/b) which produces the expected result, 1.

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`
any *T -> ?*T cast is allowed implicitly, even
when it occurs deep inside the type, and the cast
is a no-op at runtime.
in order to add this I had to make the comptime value
representation of nullable pointers the same as the
comptime value representation of normal pointers,
so that we don't have to do any recursive transformation
of values when doing this kind of cast.
Now, if a struct has any fields which require comptime,
such as `type`, then the struct is marked as requiring
comptime as well. Same goes for unions.
This means that a function will implicitly be called
at comptime if the return type is a struct which contains
a field of type `type`.
closes#586
* add assertion for trying to do @typeInfo on global error set
* remove TypeInfo.Slice
* add TypeInfo.Pointer.Size with possible values
- One
- Many
- Slice
See #770
* enable slicing for single-item ptr to arrays
* disable slicing for other single-item pointers
* enable indexing for single-item ptr to arrays
* disable indexing for other single-item pointers

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'
both ir.cpp and analyze.cpp have a function resolve_inferred_error_set,
which is a nearly exact copy-paste. This commit removes the one in ir.cpp
and exposes then one in analyze.cpp. This also allows us to make
analyze_fn_body local to analyze.cpp, as it is not used anywhere in
ir.cpp after this change
ir_make_type_info_defs already calls resolve_top_level_decl on all Tld
when building the def array. This means, that there is no reason that
analyze_fn_body is nessesary, as the fn type should have already been
resolved completly. The only thing analyze_fn_body does here, is cause
problems with generic functions.
