Convert StringMap to using StringRef for its APIs.
...
- Yay for '-'s and simplifications!
- I kept StringMap::GetOrCreateValue for compatibility purposes, this can
eventually go away. Likewise the StringMapEntry Create functions still follow
the old style.
- NIFC.

Cache dependence computation using FoldingSet.

This introduces an LDA-internal DependencePair class. The intention is,

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.

Let each target determines whether a machine instruction is dead. If true, that allows late codeine passes to delete it.

This is considered a workaround. The problem is some targets are not modeling side effects correctly. PPC is apparently one of those. This patch allows ppc llvm-gcc to bootstrap on Darwin. Once we find out which instruction definitions are wrong, we can remove the PPCInstrInfo workaround.

Revert the addition of hasNoPointerOverflow to GEPOperator.

Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.
Remove a few optimizations that depended on this flag.

Untangle a snarl that I discovered when updating the mangler,
...
starting in getCurrentFunctionEHName. Among other problems,
we would try to privative a "foo.eh" label, but end up emitting
the label as _Lfoo.eh instead of L_foo.eh on darwin. This is really
bad, and the linker has always tolerated these labels existing.
For now, just emit them as _foo.eh.
This patch also fixes problems with ".eh" labels on unnamed
functions and eliminates two strangely defined TargetAsmInfo
hooks.
