3cc87db480 A initialized global variable cannot be extern weak. However, if a global value's initializer is itself a external weak symbol, emit the weak reference.

e6ba8a819c 1. Clean up code due to changes in SwitchTo*Section(2) 
2. Added partial debug support for mingw\cygwin targets (the same as
   Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
   for storing debug info by default, thus many (runtime) libraries has
   this information included. These formats shouldn't be mixed in one binary
   ('stabs' & 'DWARF'), otherwise binutils tools will be confused.

Defaulting second arguments of SwitchTo*Section, this should make things
somehow clearer.

db06ed9156 Add debug support for X86/ELF targets (Linux). This allows llvm-gcc4 
generated object modules to be debugged with gdb. Hopefully this helps
pre-release debugging.

da7897a6c8 Do section switching right way for Mingw\Cygwin and Linux. 
This will allow (after llvm-gcc linkage fix) more dummy tests using
libstdc++ to pass on mingw :)

d1436ae792 Fixed mingw\cygwin linkonce linkage once again. 
Added workaround for linker bug with linkonce sections.
Changed sections prefix to allow linker merge them
(PE loader doesn't like too much long-named sections :) )
All of this unbreaks libstdc++ on mingw32 allowing (small)
programs to be compiled, linked and run.

6e19f80688 Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

71bc529dfa Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.

7ed816f900 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.
