stage2 translate-c: implement functions with no prototype 
stage1 translate-c actually has this wrong. When exporting a function,
it's ok to use empty parameters. But for prototypes, "no prototype"
means that it has to be emitted as a function that accepts anything,
e.g. extern fn foo(...) void;

9902b604cb Fix generation of container initializers

runtime crashes.

@sizeOf returns 0 for comptime types 
This defines `@sizeOf` to be the runtime size of a type, which means
that it is zero for types such as comptime_int, type, and (enum
literal).

1a2e02e267 fixed #2356 
const_ptr_pointee_unchecked did not take into account that if the
pointer is zero sized, then const_val->data.x_ptr.special would be
ConstPtrSpecialInvalid. This commit fixes this by also checking
that the child type of the pointer only have one possible value
and just returns that value.

fix thread local variables for non- position independent code 
This fixes comes thanks to Rich Felker from the musl libc project,
who gave me this crucial information:

"to satisfy the abi, your init code has to write the same value
to that memory location as the value passed to the [arch_prctl]
syscall"

This commit also changes the rules for when to build statically
by default. When building objects and static libraries, position
independent code is disabled if no libraries will be dynamically
linked and the target does not require position independent code.

add docs for assembly and fix global assembly parsing 
Previously, global assembly was parsed expecting it to have
the template syntax. However global assembly has no inputs,
outputs, or clobbers, and thus does not have template syntax.
This is now fixed.

This commit also adds a compile error for using volatile
on global assembly, since it is meaningless.

breaking changes to std.mem.Allocator interface API 
Before, allocator implementations had to provide `allocFn`,
`reallocFn`, and `freeFn`.

Now, they must provide only `reallocFn` and `shrinkFn`.
Reallocating from a zero length slice is allocation, and
shrinking to a zero length slice is freeing.

When the new memory size is less than or equal to the
previous allocation size, `reallocFn` now has the option
to return `error.OutOfMemory` to indicate that the allocator
would not be able to take advantage of the new size.

For more details see #1306. This commit closes #1306.

This commit paves the way to solving #2009.

This commit also introduces a memory leak to all coroutines.
There is an issue where a coroutine calls the function and it
frees its own stack frame, but then the return value of `shrinkFn`
is a slice, which is implemented as an sret struct. Writing to
the return pointer causes invalid memory write. We could work
around it by having a global helper function which has a void
return type and calling that instead. But instead this hack will
suffice until I rework coroutines to be non-allocating. Basically
coroutines are not supported right now until they are reworked as
in #1194.
