Remove more unneeded files and directories from contrib/llvm. This

still allows us to build tblgen and clang, and further reduces the
footprint in the tree.

-IRgen optimization opportunities.
-
-//===---------------------------------------------------------------------===//
-
-The common pattern of
---
-short x; // or char, etc
-(x == 10)
---
-generates an zext/sext of x which can easily be avoided.
-
-//===---------------------------------------------------------------------===//
-
-Bitfields accesses can be shifted to simplify masking and sign
-extension. For example, if the bitfield width is 8 and it is
-appropriately aligned then is is a lot shorter to just load the char
-directly.
-
-//===---------------------------------------------------------------------===//
-
-It may be worth avoiding creation of alloca's for formal arguments
-for the common situation where the argument is never written to or has
-its address taken. The idea would be to begin generating code by using
-the argument directly and if its address is taken or it is stored to
-then generate the alloca and patch up the existing code.
-
-In theory, the same optimization could be a win for block local
-variables as long as the declaration dominates all statements in the
-block.
-
-NOTE: The main case we care about this for is for -O0 -g compile time
-performance, and in that scenario we will need to emit the alloca
-anyway currently to emit proper debug info. So this is blocked by
-being able to emit debug information which refers to an LLVM
-temporary, not an alloca.
-
-//===---------------------------------------------------------------------===//
-
-We should try and avoid generating basic blocks which only contain
-jumps. At -O0, this penalizes us all the way from IRgen (malloc &
-instruction overhead), all the way down through code generation and
-assembly time.
-
-On 176.gcc:expr.ll, it looks like over 12% of basic blocks are just
-direct branches!
