* 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

And add std.math.f128_* constants.
The routines are:
__fixdfdi, __fixdfsi, __fixdfti,
__fixsfdi, __fixsfsi, __fixsfti,
__fixtfdi, __fixtfsi, __fixtfti.
These all call fixint which is a generic zig function that does the
conversion:
pub fn fixint(comptime fp_t: type, comptime fixint_t: type, a: fp_t) fixint_t
There are also a set tests:
__fixdfdi_test, __fixdfsi_test, __fixdfti_test,
__fixsfdi_test, __fixsfsi_test, __fixsfti_test,
__fixtfdi_test, __fixtfsi_test, __fixtfti_test.
system-ui is a new generic font-family for matching the font used in the operating system's native user interface. E.g. Roboto on Android, San Francisco on macOS, Segoe UI on Windows, etc.

Relevant #764
dwarf debug info is modified to use this instead of std.os.File
directly to make it easier for bare metal projects to take advantage
of debug info parsing
This reverts commit 078a0a6999.
On closer inspection, I'm not sure these values for float min/max
make sense. Why is it max instead of true_max? Why isn't it positive
and negative infinity?
Let's discuss further before committing to these changes.
it has a patch that adds an OS type, breaking the public API
this commit avoids depending on the last os type enum item,
but retains the safety assertion checks.
closes#1788
