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.
