Resizable ArrayBuffer: DataView methods

[jugglinmike]

The files in this patch are highly similar. Only the test for
DataView.prototype.getBigInt64 and DataView.prototype.setBigInt64
were written manually. The others were generated from those files via
the following script:

#!/bin/bash

set -eu

names='
BigUint64
Float32
Float64
Int16
Int32
Int8
Uint16
Uint32
Uint8
'

for name in ${names}; do
  lower=$(echo ${name} | tr '[:upper:]' '[:lower:]')
  if [ ${name} == 'BigUint64' ]; then
    replace_bigints=''
  else
    replace_bigints='-e s/\b\([0-9]\+\)n\b/\1/g'
  fi

  sed \
    -e "s/getbigint64/get${lower}/g" \
    -e "s/getBigInt64/get${name}/g" \
    ${replace_bigints} \
    ./test/built-ins/DataView/prototype/getBigInt64/resizable-buffer.js \
    > ./test/built-ins/DataView/prototype/get${name}/resizable-buffer.js

  sed \
    -e "s/setbigint64/set${lower}/g" \
    -e "s/setBigInt64/set${name}/g" \
    ${replace_bigints} \
    ./test/built-ins/DataView/prototype/setBigInt64/resizable-buffer.js \
    > ./test/built-ins/DataView/prototype/set${name}/resizable-buffer.js
done
