[XRay][compiler-rt] Support string-based config for Basic mode. Summary: This addresses http://llvm.org/PR36790. This change allows the XRay Basic Mode implementation to use the string-based initialization routine provided through `__xray_log_init_mode(...)`. In the process, we've also deprecated some flags defined for the `XRAY_OPTIONS` environment variable. We then introduce another environment variable that can control the XRay Basic Mode implementation through `XRAY_BASIC_OPTIONS`. We also rename files from `xray_inmemory_log` to `xray_basic_logging` to be more in line with the mode implementation. Depends on D46174.

Update the file headers across all of the LLVM projects in the monorepo to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636 2019-01-19 16:50:56 +08:00			`// Part of the LLVM Project, under the Apache License v2.0 with LLVM Exceptions.`
