We have a very complex process to make VDSO calls on ARM. Create a
wrapper helper function which reduces duplication and allows for
additional calls from other packages.
vdsoCall has a few differences from the original code in
walltime/nanotime:
* It does not use R0-R3, as they are passed through as arguments to fn.
* It does not save g if g.m.gsignal.stack.lo is zero. This may occur if
it called at startup on g0 between assigning g0.m.gsignal and setting
its stack.

Export cipher.xorBytes as subtle.XORBytes, for proposal #53021,
to provide fast XOR to cryptography libraries outside crypto/cipher.
Along with the move, implement the alignment check TODO
in xor_generic.go, so that systems with neither unaligned
accesses nor custom assembly can still XOR a word at a time
in word-based algorithms like GCM. This removes the need
for the separate cipher.xorWords.

GoTool was added in CL 20967, and revised in CL 21292, for #14901.
I don't fully understand what problem the GoTool function was added to
solve: the discussion on that issue was pretty sparse, but it seems
like when we run tests of GOROOT packages they always know their own
location relative to GOROOT (and thus always know where to find the
'go' tool).
Lacking that understanding, I don't want to change its behavior, but I
do at least want to verify that it resolves to the real 'go' tool in
the common case (running 'go test' on a package in GOROOT/src).

Use just 1 bit per word to record the ptr/nonptr bitmap.
Use word-sized operations to manipulate the bitmap, so we can operate
on up to 64 ptr/nonptr bits at a time.
Use a separate bitmap, one bit per word of the ptr/nonptr bitmap,
to encode a no-more-pointers signal. Since we can check 64 ptr/nonptr
bits at once, knowing the exact last pointer location is not necessary.
As a followon CL, we should make the gcdata bitmap an array of
uintptr instead of an array of byte, so we can load 64 bits of it at once.

Add a new Rewrite hook to ReverseProxy, superseding the Director hook.
Director does not distinguish between the inbound and outbound request,
which makes it possible for headers added by Director to be inadvertently
removed before forwarding if they are listed in the inbound request's
Connection header. Rewrite accepts a value containing the inbound
and outbound requests, with hop-by-hop headers already removed from
the outbound request, avoiding this problem.
ReverseProxy's appends the client IP to the inbound X-Forwarded-For
header by default. Users must manually delete untrusted X-Forwarded-For
values. When used with a Rewrite hook, ReverseProxy now strips
X-Forwarded-* headers by default.
NewSingleHostReverseProxy creates a proxy that does not rewrite the
Host header of inbound requests. Changing this behavior is
cumbersome, as it requires wrapping the Director function created
by NewSingleHostReverseProxy. The Rewrite hook's ProxyRequest
parameter provides a SetURL method that provides equivalent
functionality to NewSingleHostReverseProxy, rewrites the Host
header by default, and can be more easily extended with additional
customizations.
