6d6dd15fc3 Handle weak_extern in the JIT. This fixes 
SingleSource/UnitTests/2007-04-25-weak.c in JIT mode. The test
now passes on systems which are able to produce a correct
reference output to compare with.

f8ba919d76 Always emit a function pointer as a pointer to the function stub (if there is one). This makes it possible to compare function pointer values in lazy compilation mode. This fixes PR3043.

d735f403a0 Support for constant islands in the ARM JIT. 
Since the ARM constant pool handling supercedes the standard LLVM constant
pool entirely, the JIT emitter does not allocate space for the constants,
nor initialize the memory. The constant pool is considered part of the 
instruction stream.

Likewise, when resolving relocations into the constant pool, a hook into
the target back end is used to resolve from the constant ID# to the
address where the constant is stored.

For now, the support in the ARM emitter is limited to 32-bit integer. Future
patches will expand this to the full range of constants necessary.

112ac04abd fix a tricky bug in the JIT global variable emitter, that was triggered when JITing a variable independently of a function. This lead to sharing memory memory between functions and GVs thus changing the value of a GV could change the code in execution. more details on the ML.

a49386d8e7 On Darwin ARM, memory needs special handling to do JIT. This patch expands 
this handling to work properly for modifying stub functions, relocations
back to entry points after JIT compilation, etc..

718fcee02d Some fixes for x86-64 JIT. Make it use small code 
model, except for external calls; this makes
addressing modes PC-relative.  Incomplete.

The assertion at the top of Emitter::runOnMachineFunction
was obviously bogus (always true) so I removed it.
If someone knows what the correct test should be to cover
all the various targets, please fix.

a4de0fa539 Rewrite JIT handling of GlobalVariables so they 
are allocated in the same buffer as the code,
jump tables, etc.

The default JIT memory manager does not handle buffer
overflow well.  I didn't introduce this and I'm not
attempting to fix it here, but it is more likely to
be hit now since we're putting more stuff in the
buffer.  This affects one test that I know of so far,
MultiSource/Benchmarks/NPB-serial/is.

ef1aa7c9db Switch the PPC backend and target-independent JIT to use the libsystem 
InvalidateInstructionCache method instead of calling through
a hook on the JIT.  This is a host feature, not a target feature.
