[svn r219] Fixed: the tango/lib/gc/basic garbage collector now compiles and links into an executable (change in tango/lib/llvmdc-posix.mak), closes #5 .
Changed: removed the crappy realloc based dynamic memory runtime and started moving over to DMD style runtime support, part of moving to real GC.
Fixed: dynamic arrays now use GC runtime for allocating memory.
Fixed: new expression now use GC for allocating memory.
Changed: revamped the dynamic array support routines related to dynamic memory.
Fixed: assertions no longer create exsessive allocas.
Changed: misc. minor cleanups.
