Make LLVM_ON_UNIX and LLVM_ON_WIN32 available in the makefiles

* lib/System depends on sbrk(3), make sure we check for it.

llvm-svn: 19200

* 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

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

llvm-svn: 19148

* 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.

llvm-svn: 19136

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

* Remove --with-llvmgccdir, not needed any more
* Search path for llvm-gcc and llvm-gxx
* Compute LLVMGCCDIR based on install path of llvm-gcc

llvm-svn: 19093

* Add checks for sbrk and getpagesize functions
* Alphebetize the checks for functions

* organize programs we test for properly
* add new programs needed for documentation generation
* Adjust install paths so llvm stuff doesn't muck up /usr/local or /usr if
  $prefix is set to those.
