Summary:
Previously lldb-mi can also act as a driver like normal lldb. It needed a lot
of redundant code in the lldb-mi for that. I think that if a user wants command
line lldb driver then he/she should use the lldb for it. This change will cleanup
the code a lot. When this change goes in, it will allow us to remove some more
redundant code too.
All tests pass on Linux. Did some sanity testing on command line and with eclipse.

go/loader creates a fresh package map for each source package it imports. In
llgoi this caused binary imported packages to be imported anew for every input
line, resulting in spurious type errors and panics in go/ssa when encountering
previously imported types. Fix this by setting types.Config.Packages to our
internal package map.

These calls are usually guarded by checks for isAnnotation() but it
looks like we missed a spot. This would cause the included test to

Currently, there are no itineraries defined for ext and ins instructions.
This patch adds these itineraries and uses them in the instruction definitions.

Note that this means that llgoi does not support the case
where a package's pkgpath is different from its import path,
but I don't think this should actually happen with llgoi.

We disabled support for _Atomic because the STL had name conflicts,

Codegen for threadprivate variables (and in some other cases) may cause crash of the compiler if some diagnostic is produced later. This happens because some of the autogenerated globals are not removed from InternalVars StringMap when llvm::Module is reset.

We used to support the 2013 mangling and changed it to the more
reasonable 2015 mangling. Let's make the mangling conditional on what
version of MSVC is targeted.
This fixes PR21888.

Summary:
This change teaches isImpliedCond to infer things like "X sgt 0" => "X -
1 sgt -1". The `ConstantRange` class has the logic to do the heavy
lifting, this change simply gets ScalarEvolution to exploit that when
reasonable.

Summary:
This change splits `makeICmpRegion` into `makeAllowedICmpRegion` and
`makeSatisfyingICmpRegion` with slightly different contracts. The first
one is useful for determining what values some expression //may// take,
given that a certain `icmp` evaluates to true. The second one is useful
for determining what values are guaranteed to //satisfy// a given
`icmp`.

Targets which provide a rotate make it possible to replace a sequence of

Cleanup some bitrot in SourceLevelDebugging.rst.
- Pull the still-relevant details about individual descriptors into
LangRef.rst. Cut a lot of it to avoid over-describing the fields,
as the C++ classes and assembly format are mostly self-describing
now. If there's anything specific that I shouldn't have cut, let me
know and I'll add it back.
- Rewrite the remaining sections to refer to the new debug info
hierarchy in LangRef.rst.

Break MDExpression off of DebugNode (inherit directly from `MDNode`) and
drop the fake `DW_TAG_expression` tag in the process.
AFAICT, there's no real functionality change here. The tag was

between `MDNode`s, but in the new hierarchy we don't need that.
