portability, the --track-space option was inadvertently ignored. This patch
fixes that so that sys::Process::GetMallocUsage() is only invoked if the
--track-spaces option is given. Apparently the mallinfo() call that
GetMallocUsage() uses is *very* slow, especially when processing very large
modules like projects/llvm-test/MultiSource/Applications/kimwitu++.

* Ensure #includes are wrapped with appropriate HAVE_ guards
* Account for variations in time.h and sys/time.h inclusion.
* Add macros for getting wait(2) exit status correctly (per autoconf sugg.)
* Implement ThrowErrno in terms of strerror_r, strerror or none based on
what is available on the platform.

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.

Old versions of the C runtime somehow get loaded into the process. Make
sure they aren't searched for symbols.

Merge implementations of isValid and GetTemporaryDirectory into this file. There
is not any point having the operating system specific files for such little
variation between the Unix family of systems.

This implementation is no longer needed, its been merged to Unix/Path.cpp since
there is such little variation between the platforms.

Use the LLVM_ON_UNIX and LLVM_ON_WIN32 #defines to include the implementation

Create new variables LLVM_ON_UNIX and LLVM_ON_WIN32 so we can start getting

* When reconfiguring, make sure the config.cache file is blown away so that
its (old) values don't short-circuit doing the tests. When a reconfigure
is done, it should be done from scratch, without the cache.
* For dist-check, don't pass --with-llvmgccdir any more because configure
doesn't have this option any more.

expands to a full path name. Substitute $outputname.exp" instead and it
makes a viable temporary file name. This gets around the problem with lli
on Cygwin linking but not having any "C" library functions linked into it.

a function call at the core of the loop inline and removing unused
stack variables from an often called function. This doesn't improve things
much, the real saving will be by reducing the number of calls to this
function (100K+ when linking kimwitu++).
