Adrian Prantl d0dc528032 Remove the obsolete BlockByRefStruct flag from LLVM IR 
DIFlagBlockByRefStruct is an unused DIFlag that originally was used by
clang to express (Objective-)C block captures in debug info. For the
last year Clang has been emitting complex DIExpressions to describe
block captures instead, which makes all the code supporting this flag
redundant.

This patch removes the flag and all supporting "dead" code, so we can
reuse the bit for something else in the future.

Since this only affects debug info generated by Clang with the block
extension this mostly affects Apple platforms and I don't have any
bitcode compatibility concerns for removing this. The Verifier will
reject debug info that uses the bit and thus degrade gracefully when
LTO'ing older bitcode with a newer compiler.

This directory contains bindings for the LLVM compiler infrastructure to allow
programs written in languages other than C or C++ to take advantage of the LLVM
infrastructure--for instance, a self-hosted compiler front-end.
