This struct is larger than 256 bytes and code that copies it
consistently shows up in profiles of the compiler.

compiler-rt: compute correct integer sizes from bits at runtime

Also, accepting `align(1)` pointers ensures that the alignment is safety
checked rather than assumed.

all: migrate code to new cast builtin syntax
...
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change

compiler-rt: Set the symbol visibility
...
When we're compiling compiler_rt for any WebAssembly target, we do
not want to expose all the compiler-rt functions to the host runtime.
By setting the visibility of all exports to `hidden`, we allow the
linker to resolve the symbols during linktime, while not expose the
functions to the host runtime. This also means the linker can
properly garbage collect any compiler-rt function that does not get
resolved. The symbol visibility for all target remains the same as
before: `default`.
