Automatically do the equivalent of freeMachineCodeForFunction(F) when F is
...
being destroyed. This allows users to run global optimizations like globaldce
even after some functions have been jitted.
This patch also removes the Function* parameter to
JITEventListener::NotifyFreeingMachineCode() since it can cause that to be
called when the Function is partially destroyed. This change will be even more
helpful later when I think we'll want to allow machine code to actually outlive
its Function.

Fix http://llvm.org/PR4822 : allow module deletion after a function has been
...
compiled.
When functions are compiled, they accumulate references in the JITResolver's
stub maps. This patch removes those references when the functions are
destroyed. It's illegal to destroy a Function when any thread may still try to
call its machine code.
This patch also updates r83987 to use ValueMap instead of explicit CallbackVHs
and fixes a couple "do stuff inside assert()" bugs from r84522.

Add a ValueMap<ValueOrSubclass*, T> type. ValueMap<Value*, T> is safe to use
...
even when keys get RAUWed and deleted during its lifetime. By default the keys
act like WeakVHs, but users can pass a third template parameter to configure
how updates work and whether to do anything beyond updating the map on each
action.
It's also possible to automatically acquire a lock around ValueMap updates
triggered by RAUWs and deletes, to support the ExecutionEngine.

Move the Function*->allocated blocks map from the JITMemoryManager to the
...
JITEmitter.
I'm gradually making Functions auto-remove themselves from the JIT when they're
destroyed. In this case, the Function needs to be removed from the JITEmitter,
but the map recording which Functions need to be removed lived behind the
JITMemoryManager interface, which made things difficult.
This patch replaces the deallocateMemForFunction(Function*) method with a pair
of methods deallocateFunctionBody(void *) and deallocateExceptionTable(void *)
corresponding to the two startFoo/endFoo pairs.

Fix off-by-one in llvm::Format::print.
...
- This also shortens the Format.h implementation, and uses the print buffer
fully (it was wasting a character).
- This manifested as llvm-test failures, because one side effect was that
raw_ostream would write garbage '\x00' values into the output stream if it
happened that the string was at the end of the buffer. This meant that grep
would report 'Binary file matches', which meant the silly pattern matching
llvm-test eventually does would fail. Cute. :)

Twines: Support numeric conversion directly (uitostr, etc).
...
- Provides static constructors for doing number to string conversions without
using temporaries.
- There are several ways to do this, I think given the Twine constraints this
is the simplest one.
- One FIXME for fast number -> hex conversion.
- Added another comment on one last major bit of perf work Twines need, which
is to make raw_svector_ostream more efficient.

Make the JIT code emitter properly retry and ask for more memory when it runs
...
out of memory, and also make the default memory manager allocate more memory
when it runs out.
Also, switch function stubs and global data over to using the BumpPtrAllocator.
This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs. I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using

malloc, so there should be no functional changes to other code.
These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.
I also added some tests which helped me pinpoint some bugs.

Fix handling of max and full set.

A full set is a constant range that represents any number. If you take the

than 5 would be umax's against a value which is at least 5.
