[Lldb-commits] [PATCH] D17027: [expression evaluator] Allow runtimes to execute custom LLVM ModulePasses over the generated IR at various stages after expression compilation.

During expression evaluation, the `ClangExpressionParser` preforms a number of hard-coded fixups on the expression's IR before the module is assembled and dispatched to be run in a `ThreadPlan`.

This patch allows the runtimes to register LLVM passes to be run over the generated IR, that they may perform language or architechture-specfic fixups or analyses over the generated expression.

This makes expression evaluation for plugins more flexible and allows language-specific fixes to reside in their own module, rather than littering the expression evaluator itself with language-specific fixes.
