backport copy elision changes
This commit contains everything from the copy-elision-2
branch that does not have to do with copy elision directly,
but is generally useful for master branch.

 * All const values know their parents, when applicable, not
   just structs and unions.
 * Null pointers in const values are represented explicitly,
   rather than as a HardCodedAddr value of 0.
 * Rename "maybe" to "optional" in various code locations.
 * Separate DeclVarSrc and DeclVarGen
 * Separate PtrCastSrc and PtrCastGen
 * Separate CmpxchgSrc and CmpxchgGen
 * Represent optional error set as an integer, using the 0 value.
   In a const value, it uses nullptr.
 * Introduce type_has_one_possible_value and use it where applicable.
 * Fix debug builds not setting memory to 0xaa when storing
   undefined.
 * Separate the type of a variable from the const value of a variable.
 * Use copy_const_val where appropriate.
 * Rearrange structs to pack data more efficiently.
 * Move test/cases/* to test/behavior/*
 * Use `std.debug.assertOrPanic` in behavior tests instead of
   `std.debug.assert`.
 * Fix outdated slice syntax in docs.

simpler implementation of `&&` and `||` hints
This accomplishes the same goal, but with less changes, so that
I can backport copy elision stuff easier.

breaking API changes to all readInt/writeInt functions & more
* add `@bswap` builtin function. See #767
 * comptime evaluation facilities are improved to be able to
   handle a `@ptrCast` with a backing array.
 * `@truncate` allows "truncating" a u0 value to any integer
   type, and the result is always comptime known to be `0`.
 * when specifying pointer alignment in a type expression,
   the alignment value of pointers which do not have addresses
   at runtime is ignored, and always has the default/ABI alignment
 * threw in a fix to freebsd/x86_64.zig to update syntax from
   language changes
 * some improvements are pending #863

Sahnvour 703c6684d1 Crash fixes and small improvements to inline asm. (#1756)
* codegen: LLVMConstInlineAsm is deprecated.

* codegen: replace commas in asm constraint strings by pipes as required by LLVM.

* ir: enforce usage of '=' constraint modifier for inline assembly outputs.

Others are not currently supported and this was just asserted alter in `ir_render_asm`.

* asm: forbid comptime_int/floats as inputs in favor of explicitely sized constants.

Fixes a crash due to comptime_int/floats having no type_ref.

* asm: handle inputs with integers of <8 or non power of 2 bitsize.

We widen them to the next highest power of two.

better string literal caching implementation
We were caching the ConstExprValue of string literals,
which works if you can never modify ConstExprValues.
This premise is broken with `comptime var ...`.

So I implemented an optimization in ConstExprValue
arrays, where it stores a `Buf *` directly rather
than an array of ConstExprValues for the elements,
and then similar to array of undefined, it is
expanded into the canonical form when necessary.
However many operations can happen directly on the
`Buf *`, which is faster.

Furthermore, before a ConstExprValue array is expanded
into canonical form, it removes itself from the string
literal cache. This fixes the issue, because before an
array element is modified it would have to be expanded.

Andrew Kelley ea1b21dbdb fix linux
* error.BadFd is not a valid error code. it would always be a bug to
   get this error code.
 * merge error.Io with existing error.InputOutput
 * merge error.PathNotFound with existing error.FileNotFound.
   Not all OS's support both.
 * add os.File.openReadC
 * add error.BadPathName for windows file operations with invalid
   characters
 * add os.toPosixPath to help stack allocate a null terminating byte
 * add some TODOs for other functions to investigate removing the
   allocator requirement
 * optimize some implementations to use the alternate functions when
   a null byte is already available
 * add a missing error.SkipZigTest
 * os.selfExePath uses a non-allocating API
 * os.selfExeDirPath uses a non-allocating API
 * os.path.real uses a non-allocating API
 * add os.path.realAlloc and os.path.realC
 * convert many windows syscalls to use the W versions (See #534)

Ben Noordhuis fd75e73ee9 add f16 type
Add support for half-precision floating point operations.

Introduce `__extendhfsf2` and `__truncsfhf2` in std/special/compiler_rt.

Add `__gnu_h2f_ieee` and `__gnu_f2h_ieee` as aliases that are used in
Windows builds.

The logic in std/special/compiler_rt/extendXfYf2.zig has been reworked
and can now operate on 16 bits floating point types.

`extendXfYf2()` and `truncXfYf2()` are marked `inline` to work around
a not entirely understood stack alignment issue on Windows when calling
the f16 versions of the builtins.
