Kostya Serebryany 0e5704607b build compiler-rt with -fPIC, otherwise the run-time libs will not link with -pie, at least on linux

Daniel Dunbar 2b88e03404 lib: Add support for library wide utility functions, and make compilerrt_abort() 
a real boy.
 - The utility module needs to be included into every produced library, because
   we don't have enough dependency tracking to know exactly which other modules
   might require the utilities.

Daniel Dunbar 587b1d419d Add new build option KERNEL_USE, which compiles with -mkernel and gets propogated to CFLAGS. Use this to call panic() instead of abort() when enabled.

Daniel Dunbar bdf248d13a Allow UniversalArchs variable to be overridden on a per-config basis.

Daniel Dunbar f665b32a70 Add a VISIBILITY_HIDDEN option, which can be used to make all compiler-rt function definitions hidden/private extern.

Daniel Dunbar efd84e770b Add support for "platform" configurations, which define a suite of compiler-rt 
libraries to generate.
 - Each library may be built with different flags and for different
   architectures, and there is support for building Darwin style fat archives.

 - Uses an ambituous amount of make programming, but should be hidden to
   users and developers.

Daniel Dunbar 16c5071c6d Remove old build logic, this is going to be replaced by a more configurable mechanism shortly.

Daniel Dunbar 6bcbef6230 Rename subdir 'Target' variable to 'Implementation' to be less overloaded.

Daniel Dunbar 8e5a2f084a Add 'SelectFunctionDir' function, to select appropriate function implementation based on a configuration and architecture.

Daniel Dunbar 2d9816e44b Change subdir traversal to primarily cache information about what is available in subdirectories. 
- Rest of makefiles will move to using the information after it has been computed, instead of during subdir traversal.

Also, add 'make info-functions' target, which prints information on all the functions available in compiler-rt.

Also, add 'make help-devel' for listing help on targets intended for compiler-rt developers or direct users.

Daniel Dunbar 56e0eb9fc9 Simplify subdirectory makefiles, and be more robust by checking that they define the appropriate variables.

Daniel Dunbar 40d6f65ae1 Add basic make {help,help-hidden} targets.

Daniel Dunbar dcf5a317f1 Tidy up comments, remove whitespace, and rename 'print-%' make debugging target 
to 'make-print-%' to match LLVM.

Daniel Dunbar 85922561ee Unbreak building of assembly files (broken by my .s -> .S rename). 
- Noticed & patched by Nick Kledzik.

 - This may expose portability issues in the .S files, if so we should either
   disable them on non-Darwin, or even better make them portable.
