Applications often need the current thread id when making system calls, and some operating systems provide the notion of a thread name, which can be useful in enabling better diagnostics when debugging or logging. This patch adds an accessor for the thread id, and "best effort" getters and setters for the thread name. Since this is non critical functionality, no error is returned to indicate that a platform doesn't support thread names.

llvm/lib/Support/Unix README =========================== This directory provides implementations of the lib/System classes that are common to two or more variants of UNIX. For example, the directory structure underneath this directory could look like this: Unix - only code that is truly generic to all UNIX platforms Posix - code that is specific to Posix variants of UNIX SUS - code that is specific to the Single Unix Specification SysV - code that is specific to System V variants of UNIX As a rule, only those directories actually needing to be created should be created. Also, further subdirectories could be created to reflect versions of the various standards. For example, under SUS there could be v1, v2, and v3 subdirectories to reflect the three major versions of SUS.
