allow in-memory coercion of differently-named floats with same bits
...
For example, this allows passing a `*c_longdouble` where a `*f80` is
expected, provided that `c_longdouble` maps to `f80` for this target.

wasm: Fix @floatToInt and split overflow ops
...
As we now store negative signed integers as two's complement,
we must also ensure that when truncating a float, its value is wrapped
around the integer's size.
This also splits `@mulWithOverflow` into its own function to make
the code more maintainable and reduce branching.

flatten lib/std/special and improve "pkg inside another" logic
...
stage2: change logic for detecting whether the main package is inside
the std package. Previously it relied on realpath() which is not portable.
This uses resolve() which is how imports already work.
* stage2: fix cleanup bug when creating Module
* flatten lib/std/special/* to lib/*
- this was motivated by making main_pkg_is_inside_std false for
compiler_rt & friends.
* rename "mini libc" to "universal libc"

This improves the ABI alignment resolution code.
This commit fully enables the MachO linker code in stage3. Note,
however, that there are still miscompilations in stage3.

wasm: Store signed ints as two's complement
...
When a signed integer is negative, the integer will be stored as a two's complement,
rather than its signed value. Instead, we verify the signed bits during arithmetic operations.
This fixes signed cases of `@mulWithOverflow`.

stage2,llvm: handle softfloats in @intToFloat and @floatToInt
...
If the hw doesn't have support for exotic floating-point types such
as `f80`, we lower the call to a compiler-rt function call instead.
I've added a behavior test specifically targeting this use case which
now passes on `aarch64-macos`.
Additionally, this commit makes it possible to successfully build
stage3 on `aarch64-macos`. We can print the compiler's help message,
however, building with it needs a little bit more love still.

This commit also adds use_llvm and ofmt to the zig build system.
