* Fix codegen for optional types that decay to a pointer, the type
behaves as a boolean
* Fix comptime evaluation of zero-sized arrays, always initialize the
internal array elements
Closes#4673
Translate C: Put an alignCast in c style pointer casts to allow opaque types to cast properly in C macros
Translate C: add test case for aligning opaque types in pointer casts
Translate C: Fix @typeId -> @typeInfo
Add test case to run_translated_c for casting from pointer to opaque type
Now it will emit a compile error rather than crashing when the child
type has not been resolved properly.
Introduces `get_optional_type2` which should be used generally inside
ir.cpp.
Fix some std lib compile errors noticed by the provided test case.
Thanks @LemonBoy for the test case. Closes#4377.
Fixes#4374.
And fix most of the fallout. This also makes optional pointers not
require resolving zero bits, because the comptime value struct layout no
longer depends on whether the type has zero bits.
Thanks to @LemonBoy for the behavior test case

* rework os.sendfile and add macosx support, and a fallback
implementation for any OS.
* fix sendto compile error
* std.os write functions support partial writes. closes#3443.
* std.os pread / pwrite functions can now return `error.Unseekable`.
* std.fs.File read/write functions now have readAll/writeAll variants
which loop to complete operations even when partial reads/writes
happen.
* Audit std.os read/write functions with respect to Linux returning
EINVAL for lengths greater than 0x7fff0000.
* std.os read/write shim functions do not unnecessarily loop. Since
partial reads/writes are part of the API, the caller will be forced
to loop anyway, and so that would just be code bloat.
* Improve doc comments
* Add a non-trivial test for std.os.sendfile
* Fix std.os.pread on 32 bit Linux
* Add missing SYS_sendfile bit on aarch64
* Slices from C pointers are no longer allowzero but instead insert a runtime assertion.
* Added a test, fixed code for cases with non-allowzero C pointers
* Create new type when flipping allow_zero, sometimes we get a cached value back from adjust_ptr_len.
* Added comments, changed panic message
* Added runtime safety test.
