Minimize parameter of coerce_borrowed_pointer()
Change last parameter of `coerce_borrowed_pointer()` from `TypeAndMut` to `Mutability` (similar to `coerce_unsafe_ptr()`), since the `TypeAndMut::ty` is never used directly in this function.
Add Read/Write::can_read/write_vectored
When working with an arbitrary reader or writer, code that uses vectored
operations may end up being slower than code that copies into a single
buffer when the underlying reader or writer doesn't actually support
vectored operations. These new methods allow you to ask the reader or
witer up front if vectored operations are efficiently supported.
Currently, you have to use some heuristics to guess by e.g. checking if
the read or write only accessed the first buffer. Hyper is one concrete
example of a library that has to do this dynamically:
0eaf304644/src/proto/h1/io.rs (L582-L594)
Don't run various MIR optimizations at mir-opt-level=0
Add missing checks for mir-opt-level to non-essential MIR passes.
I verified that this can still bootstrap even with these passes disabled.
