13fd2f7128 Add detection of __dso_handle presence during configure. Use this information in the 
JITer (short path is added for darwin). This is needed to properly JIT llvm-gcc-4.2-built
binaries, since cxa_atexit is enabled by default on much more targets.

4a3a018844 VStudio compiler errors and placing Function*->ExFunc map under ManagedStatic control. 
This commit fixes two things.  One is a pair of VStudio compiler errors stemming from variables
which defined within the for loop statement and also within the body of the for loop.  I fixed these 
by renaming one of the two variables.  Additionally, I've made the Function*->ExFunc map in 
ExternalFunctions.cpp a ManagedStatic object, so that cleanup will be done on llvm_shutdown.  In repeated
uses of the interpreter, where the same Function* address may get used for completely differnet functions,
this was causing a crash.

Avoid overwriting the APInt instance with 0 bytes which causes the bitwidth
to be set to 0 (illegal) producing a subsequent assert.

2fc9ebc62a On Linux platforms and at optimization levels -O1 and above, llvm-gcc can 
turn "putchar" calls into _IO_putc calls which is a lower-level interface.
This patch allows these calls to be executed by lli in interpreter mode.

68ab99ffb6 Bitcast all the bits of a floating point value, not just one. The zero 
extension is needed because the constructor for the Destination value
causes the APInt to have a bit width of 1.

6200dc3275 1. Don't swap byte order in scanf. It isn't necessary and leads to

e1fed6f90d For PR1293: 
* Rename the FunctionType* parameter from M to FT on all the functions.
* Implement a fix for PR1293 by just asserting that library functions that
  must return pointers should have pointer typed results. This just makes
  sure that we don't attempt to use an uninitialized integer or something
  later on.

0e27441b52 Remove the insufficient code in Interpreter::create that computed the

6243e2253d Simplify things significantly because GenericValue now has a single integer 
field, of type APInt, instead of multiple integer fields. Also, get rid of
the special endianness code in StoreValueToMemory and LoadValueToMemory.
ExecutionEngine is always used to execute on the host platform so this is
now unnecessary.
