Update SV-COMP performance testing tool to 2020/2021

[tautschnig]

• Use EC2 instead of CodeBuild to avoid Docker throttling.
• Use a VPC for compatibility with current EC2 spot offerings.
• Add profiling using Linux perf as gprof doesn't seem to be working
  anymore.

• Each commit message has a non-empty body, explaining why the change was made.
• n/a Methods or procedures I have added are documented, following the guidelines provided in CODING_STANDARD.md.
• n/a The feature or user visible behaviour I have added or modified has been documented in the User Guide in doc/cprover-manual/
• Regression or unit tests are included, or existing tests cover the modified code (in this case I have detailed which ones those are in the commit message).
• n/a My commit message includes data points confirming performance improvements (if claimed).
• My PR is restricted to a single feature or bugfix.
• n/a White-space or formatting changes outside the feature-related changed lines are in commits of their own.
