Normally we rely on importing std to in turn import the root
in the start code, but when using the stage1 won't happen,
so in order to run AstGen on the root we put it into the
import_table here.
There is now a distinction between `@import` with a .zig extension and
without. Without a .zig extension it assumes it is a package name, and
returns error.PackageNotFound if not mapped into the package table.
This change reduces the amount of divergence in the compiler's main
pipeline logic enough to run AstGen for all files in the compilation,
regardless of whether the stage1 or stage2 backend is being used.
Practically, this means that all Zig code is subject to new compile
errors, such as unused local variables.
Additionally:
* remove leftover unsound asserts from recent hash map changes
* fix sub-Compilation errors not indenting correctly
Translate enum types as the underlying integer type. Translate enum constants
as top-level integer constants of the correct type (which does not necessarily
match the enum integer type).
If an enum constant's type cannot be translated for some reason, omit it.

Previously the fd parameter was ignored and so the result would not get
populated. Now it passes the fd pointer to the inline assembly so that
the results can be observed.
Before this, the continue expression of a while loop did not have the
capture variable in it, making it incorrectly emit a compile error for
not using the capture, even if it was referenced.
We can just use bitcast instead of error_to_int, int_to_error since
errorToInt and intToError do not actually do anything, just change types.
This allows us to remove 2 air ops that were the exact same as bitcast
* Remove parser error on double ampersand
* Add failing test for double ampersand case
* Add error when encountering double ampersand in AstGen
"Bit and" operator should not make sense when one of its operands
is an address.
* Check that 2 ampersands are adjacent to each other in source string
* Remove cases of unused variables in tests
* Avoid emitting the copy_file_range symbol at all to prevent link-time
errors.
* Fix a bug in the check logic, the has_copy_file_range_syscall was
set to the wrong value in case of ENOSYS
* If link_libc is true don't fall-back to the raw syscall approach,
there's no policy about what to do in this case but let's follow what
the other impls do.
Fixes#9146
