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

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.

translate-c: Correctly translate enum init values, addressing #1360 ( #1377 )
...
* translate-c: Correctly translate enum init values
* translate-c: Test enum initialization
* translate-c: Flip to positive using APSInt builtins
* src/translate_c.cpp: correctly bridge llvm::APSInt with Zig BigInt;
ACHTUNG: llvm::APSInt stores an int's sign inside of its getRawData; Internally to Zig we store an integer's sign outside of getRawData! (~aps_int) calls .flip() internally on the raw data to match Zig.
* test/translate_c.zig: enum: add wider range of values (u64) to try;

The logic in std/special/compiler_rt/extendXfYf2.zig has been reworked

`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.

nullable pointers follow const-casting rules
...
any *T -> ?*T cast is allowed implicitly, even
when it occurs deep inside the type, and the cast
is a no-op at runtime.
in order to add this I had to make the comptime value
representation of nullable pointers the same as the
comptime value representation of normal pointers,
so that we don't have to do any recursive transformation
of values when doing this kind of cast.

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`.

disallow unknown-length pointer to opaque

This also means that translate-c has to detect when a pointer to
opaque is happening, and use `*` instead of `[*]`.

use * for pointer type instead of &
...
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'

fixed #1009
...
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.
