* add implicit cast from `*@Frame(func)` to `anyframe->T` or `anyframe`.
* add implicit cast from `anyframe->T` to `anyframe`.
* `resume` works on `anyframe->T` and `anyframe` types.
It used to be that usingnamespace was only allowed at top level. This
made it OK to put the state inside the AST node data structure. However,
now usingnamespace can occur inside any aggregate data structure, and
therefore the state must be in the TopLevelDeclaration rather than in
the AST node.
There were two other problems with the usingnamespace implementation:
* It was passing the wrong destination ScopeDecl, so it could cause an
incorrect error such as "import of file outside package path".
* When doing `usingnamespace` on a file that already had
`pub usingnamespace` in it would "steal" the usingnamespace, causing
incorrect "use of undeclared identifier" errors in the target file.

unsigned bits;
and expand @sqrt
This revealed that the accuracy of ln is not as good as the current algorithm in
musl and glibc, and should be ported again.
v2: actually include tests
v3: fix reversal of in and out arguments on f128M_sqrt()
add test for @sqrt on comptime_float
do not include @nearbyInt() until it works on all targets.
