Mehdi Amini bb6805d263 Update Kaleidoscope tutorial and improve Windows support
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).

Lang Hames ad4a911fea [ExecutionEngine][MCJIT][Orc] Replace RuntimeDyld::SymbolInfo with JITSymbol.
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.

Lang Hames 656532075b [Orc] Add conversion to/from RuntimeDyld::SymbolInfo for JITSymbol.
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.

Lang Hames db0551e3ab [Kaleidoscope][BuildingAJIT] Finish off Chapter 1.
* 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.

Lang Hames 9ed5f00026 [KaleidoscopeJIT][BuildingAJIT] Remove some copy-pasta from Chapter 1.
This text was accidentally left in when the original document was copied from
Chapter 7 of the Kaleidoscope language series.

Lang Hames 9d4ea6df8b [Kaleidoscope][BuildingAJIT] Shorten the name of the BuildingAJIT tutorial
series.

The original name was pretty long, and likely to look awkward as more
chapters get added.

Lang Hames 7331cc3774 [Kaleidoscope] Add an initial "Building an ORC JIT" tutorial chapter.
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.
