* Add CAN_DLOPEN_SELF so we can determine if dlopen(0) will open the
program or not.
* Correct a warning messages to be a little more specific on what it checks

* Move implementation of sys::PreventCoreFiles function to this file from
the now defunct SysConfig abstraction.

SysConf abstraction was pointless because it had a single function in it that
pertained only to the current process. So merge it into the Process abstraction
and remove the files completely.

* Add checks for sterror and strerror_r functions
* Add check to determine if /dev/zero is needed for allocating RWX memory.

* Make sure all headers used by lib/System have checks
* Use "standard" autoconf checks for certain problematic headers
For PR432:
* Resurrect --with-llvmgccdir so a specific llvm-gcc/llvm-g++ installation
can be specified.

Create new variables LLVM_ON_UNIX and LLVM_ON_WIN32 so we can start getting
rid of reliance upon a symbolic link to switch implementations in lib/System

* Add GetMallocUsage as a wrapper around mallinfo()
* Add GetTotalMemoryUsage to get approximate RSS size
* Add GetTimeUsage to get elapsed/system/user time

Incorporate the abilities of RunPRogramWithTimeout into
sys::Program::ExecuteAndWait so that redirection and a timeout are optionally
supported.

Replace RunProgramWithTimeout with an inline function that calls
sys::Program::ExecuteAndWait. This is now just a convenience function.

* Make the OutputC and OutputAsm functions work with sys::Path for the output
file name instead of using std::string.
* Get rid of extraneous "toString" calls.
* Change "removeFile" to sys::Path::destroyFile()
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19000 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the "removeFile" function, now implemented by the
sys::Path::destroyFile method.
* Make the FileRemove work with a sys::Path instead of a std::string

createTemporaryFile semantics where it doesn't create a fully unique name
if the basename doesn't exist. This functionality is now optionally
provided by the boolean reuse_current parameter to createTemporaryFile and
makeUnique. The default values differ because of the way these functions
are used in LLVM.
