CL 91097 added TestNoCache. However, this
test is failing on Plan 9 because the HOME
environment variable doesn't contain the
home directory where the Go cache is located.
This change fixes the TestNoCache test

preparePanic must set all registers expected by Go runtime conventions
in case the sigpanic is being injected into C code. However, on
mips64x it fails to restore RSB (R28). As a result, if C code modifies
RSB and then raises a signal that turns into a sigpanic call, sigpanic
may crash when it attempts to lock runtime.debuglock (the first global
it references).
Fix this by restoring RSB in the signal context using the same
convention as main and sigtramp.

Currently, gentraceback suppresses the "unexpected return pc" error
for sigpanic's caller if the M was running C code.
However, there are various situations where a sigpanic is injected
into C code that can cause traceback to unwind *past* the sigpanic
before realizing that it's in trouble (the traceback beyond the
sigpanic will be wrong).
Rather than try to fix these issues for Go 1.10, this CL simply
disables complaining about unexpected return PCs if we're in cgo
regardless of whether or not they're from the sigpanic frame. Go 1.9
never complained about unexpected return PCs when printing, so this is
simply a step closer to the old behavior.
This should fix the openbsd-386 failures on the dashboard, though this

The compiler allows code to have multiple differently-typed views of a
single argument. For instance, if we have
func f(x float64) {
y := *(*int64)(unsafe.Pointer(&x))
...
}
Then in SSA we get two OpArg ops, one with float64 type and one with
int64 type.
The compiler will try to reuse argument slots for spill slots. It
checks that the argument slot is dead by consulting an interference
graph.
When building the interference graph, we normally ignore cross-type
edges because the values on either end of that edge can't be allocated
to the same slot. (This is just a space-saving optimization.) This
rule breaks down when one of the values is an argument, because of the
multiple views described above. If we're spilling a float64, it is not
enough that the float64 version of x is dead; the int64 version of x
has to be dead also.
Remove the optimization of not recording interference edges if types
don't match. That optimization is incorrect if one of the values
connected by the edge is an argument.

Currently, startpanic_m (which prepares for an unrecoverable panic)
goes out of its way to make it possible to allocate during panic
handling by allocating an mcache if there isn't one.
However, this is both potentially dangerous and unnecessary.
Allocating an mcache is a generally complex thing to do in an already
precarious situation. Specifically, it requires obtaining the heap
lock, and there's evidence that this may be able to deadlock (#23360).
However, it's also unnecessary because we never allocate from the
unrecoverable panic path.
This didn't use to be the case. The call to allocmcache was introduced
long ago, in CL 7388043, where it was in preparation for separating Ms
and Ps and potentially running an M without an mcache. At the time,
after calling startpanic, the runtime could call String and Error
methods on panicked values, which could do anything including
allocating. That was generally unsafe even at the time, and CL 19792
fixed this be pre-printing panic messages before calling startpanic.
As a result, we now no longer allocate after calling startpanic.
This CL not only removes the allocmcache call, but goes a step further
to explicitly disallow any allocation during unrecoverable panic
handling, even in situations where it might be safe. This way, if
panic handling ever does an allocation that would be unsafe in unusual
circumstances, we'll know even if it happens during normal
circumstances.
This would help with debugging #23360, since the deadlock in
allocmcache is currently masking the real failure.
Beyond all.bash, I manually tested this change by adding panics at
various points in early runtime init, signal handling, and the
scheduler to check unusual panic situations.
