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.
