fix structs that contain types which require comptime
...
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`.

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'

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.

So, Zig does not support ReleaseFast or ReleaseSafe for coroutines yet.
Luckily, Clang users are running into the same crashes, so folks from the LLVM
community are working on fixes. If we're really lucky they'll be fixed in 6.0.1.
Otherwise we can hope for 7.0.0.

introduce std.heap.ArenaAllocator and std.heap.DirectAllocator
...
* DirectAllocator does the underlying syscall for every allocation.
* ArenaAllocator takes another allocator as an argument and
allocates bytes up front, falling back to DirectAllocator with
increasingly large allocation sizes, to avoid calling it too often.
Then the entire arena can be freed at once.
The self hosted parser is updated to take advantage of ArenaAllocator
for the AST that it returns. This significantly reduces the complexity
of cleanup code.
docgen and build runner are updated to use the combination of
ArenaAllocator and DirectAllocator instead of IncrementingAllocator,
which is now deprecated in favor of FixedBufferAllocator combined
with DirectAllocator.
The C allocator calls aligned_alloc instead of malloc, in order to
respect the alignment parameter.
Added asserts in Allocator to ensure that implementors of the
interface return slices of the correct size.
Fixed a bug in Allocator when you call realloc to grow the allocation.

std lib: modify allocator idiom
...
Before we accepted a nullable allocator for some stuff like
opening files. Now we require an allocator.
Use the mem.FixedBufferAllocator pattern if a bound on the amount
to allocate is known.
This also establishes the pattern that usually an allocator is the
first argument to a function (possibly after "self").

remove arrow:

add void:

ir: new pass iteration strategy
...
Before:
* IR basic blocks are in arbitrary order
* when doing an IR pass, when a block is encountered, code
must look at all the instructions in the old basic block,
determine what blocks are referenced, and queue up those
old basic blocks first.
* This had a bug (See #667 )
Now:
* IR basic blocks are required to be in an order that guarantees
they will be referenced by a branch, before any instructions
within are referenced.
ir pass1 is updated to meet this constraint.
* When doing an IR pass, we iterate over old basic blocks
in the order they appear. Blocks which have not been
referenced are discarded.
* After the pass is complete, we must iterate again to look
for old basic blocks which now point to incomplete new
basic blocks, due to comptime code generation.
* This last part can probably be optimized - most of the time
we don't need to iterate over the basic block again.

command line args, we could leave off this "no inline"
attribute.
* add i29 and u29 primitive types. u29 is the type of alignment,
so it makes sense to be a primitive.
probably in the future we'll make any `i` or `u` followed by
digits into a primitive.
* add `aligned` functions to Allocator interface
* add `os.argsAlloc` and `os.argsFree` so that you can get
a `[]const []u8`, do whatever arg parsing you want, and then free
it. For now this uses the other API under the hood, but it could
be reimplemented to do a single allocation.
* add tests to make sure command line argument parsing works.
