r274441 introduced Chapter 10 of "Implementing a Language with LLVM" tutorial,
which caused all files in the tutorial to start using two digit numbering. But
many links were not changed and therefore appear to be broken. This patch
addresses described issue.
As a result, following command does not produce any output anymore:
$ grep -nR '<LangImpl[0-9].html>' ./docs/tutorial/

Many quoted code blocks were not in sync with the actual toy.cpp
files. Improve tutorial text slightly in several places.
Added some step descriptions crucial to avoid crashes (like
InitializeNativeTarget* calls).
Solve/workaround problems with Windows (JIT'ed method not found, using
custom and standard library functions from host process).

This patch replaces RuntimeDyld::SymbolInfo with JITSymbol: A symbol class
that is capable of lazy materialization (i.e. the symbol definition needn't be
emitted until the address is requested). This can be used to support common
and weak symbols in the JIT (though this is not implemented in this patch).
For consistency, RuntimeDyld::SymbolResolver is renamed to JITSymbolResolver.
For space efficiency a new class, JITEvaluatedSymbol, is introduced that
behaves like the old RuntimeDyld::SymbolInfo - i.e. it is just a pair of an
address and symbol flags. Instances of JITEvaluatedSymbol can be used in
symbol-tables to avoid paying the space cost of the materializer.

This tidies up some code that was manually constructing RuntimeDyld::SymbolInfo
instances from JITSymbols. It will save more mess in the future when
JITSymbol::getAddress is extended to return an Expected<TargetAddress> rather
than just a TargetAddress, since we'll be able to embed the error checking in
the conversion.

* Various tidy-up and streamlining of existing discussion.
* Describes findSymbol and removeModule.
Chapter 1 is now rough but essentially complete in terms of content.
Feedback, patches etc. very welcome.

This text was accidentally left in when the original document was copied from
Chapter 7 of the Kaleidoscope language series.

This is a work in progress - the chapter text is incomplete, though
the example code compiles and runs.
Feedback and patches are, as usual, most welcome.
