[lit] support unsetting env variables (again!) This is an updated version of https://reviews.llvm.org/D22144 by @jlpeyton. The patch was accepted but not landed. This is useful functionality and I would like to use this to enable lit tests for environment variable behaviour. Differential Revision: https://reviews.llvm.org/D36403 llvm-svn: 311180

[lit] Diagnose insufficient args to internal env Without this patch, failing to provide a subcommand to lit's internal `env` results in either a python `IndexError` or an attempt to execute the final `env` argument, such as `FOO=1`, as a command. This patch diagnoses those cases with a more helpful message. Reviewed By: stella.stamenova Differential Revision: https://reviews.llvm.org/D66482 llvm-svn: 369620

[lit] Print internal env commands Without this patch, the internal `env` command removes `env` and its args from the command line while parsing it. This patch modifies a copy instead so that the original command line is printed. Reviewed By: stella.stamenova, rnk Differential Revision: https://reviews.llvm.org/D65624 llvm-svn: 367752
