This updates all linker tests to include `no_entry` as well as changes
all tests to executable so they do not need to be updated later when
the in-house WebAssembly linker supports dynamic libraries.
When linking a WebAssembly binary using wasm-ld, we will now correctly pass
--shared when building a dynamic library and --pie when `-fpic` is given.
This is a breaking change and users who currently build dynamic libraries
for WebAssembly but wish to have an executable without a main, should use
build-exe instead while supplying `-fno-entry`.
We also verify the user does not supply --export-memory when -dynamic is
enabled. By default we set this flag now to 'false' when `-dynamic` is used
to ensure we do not enable it as it's enabled by default for regular
WebAssembly binaries.
This adds support for the `-fno-entry` and `-fentry` flags respectively, for
zig build-{exe/lib} and the build system. For `zig cc` we use the `--no-entry`
flag to be compatible with clang and existing tooling.
In `start.zig` we now make the main function optional when the target is
WebAssembly, as to allow for the build-exe command in combination with
`-fno-entry`.
When the execution model is set, and is set to 'reactor', we now verify
when an entry name is given it matches what is expected. When no entry
point is given, we set it to `_initialize` by default. This means the user
will also be met with an error when they use the reactor model, but did
not provide the correct function.
Arrays are currently always passed by reference, this means that we
always keep the value in linear memory and never load it to Wasm's
stack. Scalar values however do get lowered to Wasm's stack.
This means when bitcasting from an array to a scalar value, we must
load the memory of the array as such scalar type. To bitcast
a scalar type to an array, we allocate a new temporary in the
linear data segment, and then store the scalar value there.
Use inline to vastly simplify the exposed API. This allows a
comptime-known endian parameter to be propogated, making extra functions
for a specific endianness completely unnecessary.
- Add resolveUnionAlignment, to resolve a union's alignment only, without triggering layout resolution.
- Update resolveUnionLayout to cache size, alignment, and padding. abiSizeAdvanced and abiAlignmentAdvanced
now use this information instead of computing it each time.

As suggested by mlugg, always returns `error.NeedLazy`. If this has a
performance impact, it could be replaced by adding lazy handling to
`comptimeOnlyAdvanced`.
