12a7a0d76f omit safety check when incrementing for loop counter 
Since for loops are statically analyzed to have an upper bound, and the
loop counter is a usize, it is impossible for it to overflow.

74db8c2e83 omit safety checks for element access in for loops 
One of the main points of for loops is that you can safety check the
length once, before entering the loop, and then safely assume that every
element inside the loop is in bounds.

In master branch, the safety checks are incorrectly intact even inside
for loops. This commit fixes it. It's especially nice with multi-object
loops because the number of elided checks is N * M where N is how many
iterations and M is how many objects.

321ccbdc52 Sema: implement for_len 
This also makes another breaking change to for loops: in order to
capture a pointer of an element, one must take the address of array
values. This simplifies a lot of things, and makes more sense than how
it was before semantically.

It is still legal to use a for loop on an array value if the
corresponding element capture is byval instead of byref.

841add6890 AstGen: finish multi-object for loops 
This strategy uses pointer arithmetic to iterate through the loop. This
has a problem, however, which is tuples. AstGen does not know whether a
given indexable is a tuple or can be iterated based on contiguous
memory. Tuples unlike other indexables cannot be represented as a
many-item pointer that is incremented as the loop counter.

So, after this commit, I will modify AstGen back closer to how @vexu had
it before, using a counter and array element access.

faa44e2e58 AstGen: rework multi-object for loop 
* Allow unbounded looping.
* Lower by incrementing raw pointers for each iterable rather than
  incrementing a single index variable. This elides safety checks
  without any analysis required thanks to the length assertion and
  lowers to decent machine code even in debug builds.
  - An "end" value is selected, prioritizing a counter if possible,
    falling back to a runtime calculation of ptr+len on a slice input.
* Specialize on the pattern `0..`, avoiding an unnecessary subtraction
  instruction being emitted.
* Add the `for_check_lens` ZIR instruction.

6d71d79dc2 Package: store package name directly 
By @Vexu's suggestion, since fetching the name from the parent package
is error-prone and complex, and optimising Package for size isn't really
