Cherry-pick upstream patch:
Fix Undefined Behavior in hash.h
hash.h:200:27, left shift of 250 by 24 places cannot be represented in type 'int'

`Toxic' means dtrace forbids D scripts from even attempting to read
or write at them.
Previously we considered [0, VM_MIN_KERNEL_ADDRESS) toxic, but
VM_MIN_KERNEL_ADDRESS is only the minimum address of the kernel map;
the direct-mapped region lies below it, and with PMAP_MAP_POOLPAGE we
allocate virtual pages for pool backing directly from physical pages
through the direct-mapped region. Also, this did not consider I/O
mappings to be toxic, which they probably should be.
Instead, treat:
[0, AARCH64_KSEG_START)
and
[VM_KERNEL_IO_ADDRESS, 0xfff...ff)
as toxic. (The upper bound for 0xfff...ff ought to be inclusive, not
exclusive, but I think we'll need another mechanism for expressing
that to dtrace!)
Given that we have just checked vallen < len, it can never be the case
that vallen >= len + sizeof(rhostname). This fixes the check so we
actually avoid overflowing the rhostname array.

aarch64 fbt_invop doesn't actually use the argument, but it would
make more sense for it to be the return value and/or first argument
register. Certainly it's not `eax'!

It should be an administrative flag only.

sysv4.h already overrides PREFERRED_STACK_BOUNDARY b/c SYSV ABI
requires 16 bytes alignment for %sp anyway and so we already get that
for free.
More importantly this also fixes alloca() in GCC 8, that was somehow
confused by that STACK_BOUNDARY value we had and created a buffer that
overlapped top local variable slots.
The prototypes in libexecinfo's unwind.h do not match those commonly
used (e.g. by gcc, clang, GNU libunwind, LLVM libunwind...), causing
C++ programs to fail to build on type mismatches (e.g. compiler-rt,
libc++abi). Rather than providing our own header, reuse the one
included in gcc.
