The testcases as written made assumptions about size_t and long
being invalid for use with "%u".
We only need some invalid type, so this patch converts them to
attempt a "const char *" with "%u", which should be invalid for
every target.

Since the name siginfo winds up in runtime.inc, this avoids a name
collision on systems that define "struct siginfo" in the system header
files.

If a jump always falls through but that cannot be optimised away, like
is the case with the PowerPC bdnz insn if its jump target is the same as
the fallthrough, sched gets confused if it schedules some instructions
from before that jump instruction to behind it: it splits the
fallthrough branch, but the jump target isn't updated, and things fall
apart as in the PR. This patch fixes it.
The second patch fragment makes -fsched-verbose=N work for N>=4; the
currently scheduled fragment can now contain a label. Everything else
seems to work fine with that.

fallthrough.

This is a start of implementing type aliases (`type T1 = T2`) in the
Go frontend. This is incomplete, in that the reflection information
is not updated for an embedded type alias. It is also not well
tested. Finally, the change to the language has not been approved.
This should be regarded as preliminary work for experimental use.
Update golang/go#18130.

Compiler changes:
* Change map assignment to use mapassign and assign value directly.
* Change string iteration to use decoderune, faster for ASCII strings.
* Change makeslice to take int, and use makeslice64 for larger values.
* Add new noverflow field to hmap struct used for maps.
Unresolved problems, to be fixed later:
* Commented out test in go/types/sizes_test.go that doesn't compile.
* Commented out reflect.TestStructOf test for padding after zero-sized field.
