System.CompomentModel.Component.cs: Make disposedEvent key static
[jit] Add a simple loop invariant loop motion pass for use with LLVM, which moves loop invariant instructions out of loop headers into the preceeding bblock.
[llvm] Mark the load generated by OP_AOTCONST as invariant.
Do not justify the text
[llvm] Rename the MONO_INST_CONSTANT_LOAD flag to MONO_INST_INVARIANT_LOAD for consistency with LLVM.
[llvm] Update list of optimizations passed to 'opt'.
[llvm] Use i64*/i32* as the LLVM type of objrefs instead of i64/i32, the basicaa LLVM pass cannot see through the inttoptr casts we were emitting before loads.
[aot] Avoid emitting a 'methods' symbol using .set methods, clang's integrated assembler doesn't seem to support it.
[aot] Use clang as the assembler on osx.
[llvm] Add the strip-dead-prototypes pass to remove unused intrinsics definitions from the .bc file.
[aot] Use temp.bc/temp.opt.bc instead of temp.s.bc/temp.s.opt.bc as llvm temporary file names.
[aot] Clean up the linker invocation code a bit.
[aot] Remove -mattr=-avx flag to llc on amd64+osx, its no longer needed.
