This reverts commit 133abdeda2994886c3476a3faf53f8a911513b32 but keeps
the tests disabled for the wasm target, which is the only configuration
that seems to fail, even though the error looks like a frontend error.
For representing struct field default values and array/pointer type
sentinel values, we use `*const anyopaque`, since there is no way for
`std.builtin.Type.StructField` etc to refer back to its `type` field.
However, when introspecting a type, this is quite awkward due to the
pointer casts necessary.
As such, this commit renames the `sentinel` fields to `sentinel_ptr`,
and the `default_value` field to `default_value_ptr`, and introduces
helper methods `sentinel()` and `defaultValue()` to load the values.
These methods are marked as `inline` because their return value, which
is always comptime-known, is very often required at comptime by use
sites, so this avoids having to annotate such calls with `comptime`.
This is a breaking change, although note that 0.14.0 is already a
breaking release for all users of `std.builtin.Type` due to the union
fields being renamed.
Implementing the changes from the prior commit, to prepare for the
following commit.
This also means that zig1 now uses the new value interpret mode, so
that adding and removing fields from `std.builtin` types is easier.

This was done by regex substitution with `sed`. I then manually went
over the entire diff and fixed any incorrect changes.
This diff also changes a lot of `callconv(.C)` to `callconv(.c)`, since
my regex happened to also trigger here. I opted to leave these changes
in, since they *are* a correct migration, even if they're not the one I
was trying to do!
This matches established naming conventions. Now is an opportune time to
make this change, since we're already performing breaking changes to
`std.builtin.Type`.
this logic has not yet been ported to the new design, but the logic is
safe and sound in the git history and does not need to also live as
commented out code
fix calculation of alignment and size
include __tls_align and __tls_size globals along with __tls_base
include them only if the TLS segment is emitted
add missing reloc logic for memory_addr_tls_sleb
fix name of data segments to include only the prefix
