Description of problem:
I'm building github.com/nats-io/gnatsd 2.0.0-RC8 with:

go build -buildmode pie -compiler gc '-tags=rpm_crashtraceback ' -ldflags '-X github.com/nats-io/gnatsd/version.tag=v2.0.0-RC8 -X github.com/nats-io/gnatsd/version=2.0.0 -B 0x51f0a6c96fb7745750f72bd94ce56793deb3d943 -extldflags '\''-Wl,-z,relro -Wl,--as-needed -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld '\''' -a -v -x -o /builddir/build/BUILD/nats-server-2.0.0-RC8/_build/bin/gnatsd github.com/nats-io/gnatsd

Build progress until it hits this error:

Build was working with Golang 1.12.7 under the same conditions. Other arches beside aarch64 are working correctly.

Version-Release number of selected component (if applicable):
golang-1.13-0.beta1.2.fc31

How reproducible:
Always

Steps to Reproduce:

mkdir issue33355
cd issue33355
git clone https://github.com/nats-io/gnatsd
cd gnatsd
GOARCH=arm64 go build

Actual results:
_build/src/github.com/nats-io/gnatsd/server/gateway.go:2119:10: internal compiler error: '(*client).sendMsgToGateways': no register available for v418 = LoweredAtomicAdd32Variant <uint32,mem> v344 v145 v407

Expected results:
Build success.
