compiler: implement deferring of immediately-applied closures
...
This is a common operation:
freevar := ...
defer func() {
println("I am deferred:", freevar)
}()
The function is thus an immediately applied closure. Only this form is
currently supported, support for regular (fat) function pointers should
be trivial to add but is not currently implemented as it wasn't
necessary to get fmt to compile.

ir: fix interface call edge case
...
A function on a type that is put in an interface must not be assumed to
not need a context pointer when it isn't directly put in a function
pointer, because the interface call side won't know this and pass an
extra parameter with that extra function pointer.
This is usually not a problem but WebAssembly has strict checks on
function signatures so this resulted in an error when running
src/examples/test/test.go.

compiler: special slice bounds check for 64-bit numbers
...
It is allowed to index with an int64 even on a 32-bit platform, so we
have to handle that case. But make sure the normal case isn't penalized
by using 32-bit numbers when possible.

Bigger hashmaps (size > 8) use multiple buckets in a chain. The lookup

first bucket for key equality.

compiler: correctly generate global hashmaps of size > 8

Static map generation used the last bucket instead of the first bucket

multiple buckets (size > 8).

compiler: optimize runtime.stringToBytes calls
...
This optimization makes sure the following pattern doesn't do a heap
allocation (assuming Write doesn't modify the slice):
var w *machine.UART = ...
w.Write([]byte("foo"))
As long as Write doesn't modify the slice and LLVM can detect this, a
call to runtime.stringToBytes with the necessary allocation + copy is
avoided.
