Reland r23732: ARM64: Fix and improve --trace-sim register trace.

- Use standard names (except that our GREY is the standard BLACK).
- Make non-bold colours explicit, otherwise the boldness can carry over
  into subsequent colour declarations.
- I've moved some colours around to make them consistent. Register value
  updates (which are very common) now stand out less than they did,
  making the less-common (and arguably more important) debug
  announcements appear brighter.
  - FP registers and values are now magenta.
  - Integer registers and values are now cyan.
  - Memory accesses are now blue.
- LOG_WRITE prints the source register for stores.
- Loads are logged with a format similar to that used for stores.
  Specifically, the memory address is printed alongside the new register
  value.
- Updates to D registers print the raw bits as well as the double value.
  Updates to S registers print the raw bits as well as the float value.
  (Previously, we printed both double and float interpretations of the
  bits, which was a bit cluttered.)

ARM64: Fix and improve --trace-sim register trace.

- Use standard names (except that our GREY is the standard BLACK).
- Make non-bold colours explicit, otherwise the boldness can carry over
  into subsequent colour declarations.
- I've moved some colours around to make them consistent. Register value
  updates (which are very common) now stand out less than they did,
  making the less-common (and arguably more important) debug
  announcements appear brighter.
  - FP registers and values are now magenta.
  - Integer registers and values are now cyan.
  - Memory accesses are now blue.
- LOG_WRITE prints the source register for stores.
- Loads are logged with a format similar to that used for stores.
  Specifically, the memory address is printed alongside the new register
  value.
- Updates to D registers print the raw bits as well as the double value.
  Updates to S registers print the raw bits as well as the float value.
  (Previously, we printed both double and float interpretations of the
  bits, which was a bit cluttered.)

Add cwd to all shell commands in auto roll scripts.

The v8 root directory is assumed to be the default cwd. All
commands executed in another directory (e.g. the chromium
checkout) need an explicit specification (also in the
tests).

This also fixes several small testing and robustness bugs:
- Get rid of all 'rm ...' shell calls
- Don't leak tmp files/dirs
- Add some forgotten shell calls to the test expectations
- Hardcode the DEPS location (must always be
chromium_dir/DEPS)
- Expect correct return code when terminating gracefully
