amend: fix amend with copies in extras

If copy information is stored only in the commit extras and not in
filelogs, then they get lost on amend if the file wasn't also modified
in the working copy. That's because we create `filectx` object from
the old commit in those cases, and the `.copysource()` of such objects
read only from the filelog. This patch fixes it by always creating a
new `memfilectx` in these cases, passing the calculated copy
information to it.

  $ hg help -e perf
  perf extension - helper extension to measure performance
  
  Configurations
  ==============
  
  "perf"
  ------
  
  "all-timing"
      When set, additional statistics will be reported for each benchmark: best,
      worst, median average. If not set only the best timing is reported
      (default: off).
  
  "presleep"
    number of second to wait before any group of runs (default: 1)
  
  "pre-run"
    number of run to perform before starting measurement.
  
  "profile-benchmark"
    Enable profiling for the benchmarked section. (The first iteration is
    benchmarked)
  
  "run-limits"
    Control the number of runs each benchmark will perform. The option value
    should be a list of '<time>-<numberofrun>' pairs. After each run the
    conditions are considered in order with the following logic:
  
        If benchmark has been running for <time> seconds, and we have performed
        <numberofrun> iterations, stop the benchmark,
  
    The default value is: '3.0-100, 10.0-3'
  
  "stub"
      When set, benchmarks will only be run once, useful for testing (default:
      off)

--------------------

(perf discovery has some spurious output)

  $ hg perfdiscovery . --config perf.stub=no --config perf.run-limits='0.000000001-1' --config perf.pre-run=0

test  profile-benchmark option
------------------------------

Function to check that statprof ran
  $ statprofran () {
  >   egrep 'Sample count:|No samples recorded' > /dev/null
  > }
  $ hg perfdiscovery . --config perf.stub=no --config perf.run-limits='0.000000001-1' --config perf.profile-benchmark=yes 2>&1 | statprofran
