Previously, it pointed to the start of the current token, but this made
it difficult to tell where the error occurred when it was, say, in the
middle of a string.
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* Fix outdated slice syntax in docs.
* 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 #863closes#638closes#1733
std lib API changes
* io.InStream().readIntNe renamed to readIntNative

* added mem.nativeToBig
* 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.
