This change is seemingly insignificant but I actually agonized over this
for three days. Some other things I considered:
* (status quo in master branch) make Compile step creation functions
accept a Target.Query and delete the ResolvedTarget struct.
- downside: redundantly resolve target queries many times
* same as before but additionally add a hash map to cache target query
resolutions.
- downside: now there is a hash map that doesn't actually need to
exist, just to make the API more ergonomic.
* add is_native_os and is_native_abi fields to std.Target and use it
directly as the result of resolving a target query.
- downside: they really don't belong there. They would be available
as comptime booleans via `@import("builtin")` but they should not
be exposed that way.
With this change the downsides are:
* the option name of addExecutable and friends is `target` instead of
`resolved_target` matching the type name.
- upside: this does not break compatibility with existing build
scripts
* you likely end up seeing `target.result.cpu.arch` rather than
`target.cpu.arch`.
- upside: this is an improvement over `target.target.cpu.arch` which
it was before this commit.
- downside: `b.host.target` is now `b.host.result`.
