If the source register is live after the copy being spilled, there is no
point to hoisting it.  Hoisting inside a basic block only serves to
resolve interferences by shortening the live range of the source.

Don't attach annotations to MCInst's.  Instead, have the disassembler return, and the printer accept, an annotation string which can be passed through if the client cares about annotations.

gold plugin is built with Large File Support (sizeof(off_t) == 64 on i686)
and the rest of LLVM is built w/o Large File Support
(sizeof(off_t) == 32 on i686) which corrupts the stack.

When -split-spill-mode is enabled, spill hoisting is performed by
SplitKit instead of by InlineSpiller.  This hidden command line option
is for testing the splitter spill mode.

DWARF: Put all the pieces we have together and provide a single accessor to DIContext that provides line information when given an address.

DWARF: Remove accessors that parse the whole line table section in one go, this can't possibly work.

The address size is specified by the compile unit associated with a line table, there is no global address size.

The the MC disassembler C API to print in verbose mode.  Perhaps there should be a parameter to request verbose mode?

Add support for stored annotations to MCInst, and provide facilities for MC-based InstPrinters to print them out.  Enhance the ARM and X86 InstPrinter's to do so in verbose mode.

Fix the stats counters to reflect that.

take into consideration the presence of AVX. This change, together with
the SSEDomainFix enabled for AVX, makes AVX codegen to always (hopefully)
emit the same code as SSE for 128-bit vector ops. I don't
have a testcase for this, but AVX now beats SSE in performance for
128-bit ops in the majority of programas in the llvm testsuite

The number of spills could go negative since a folded COPY is just a
spill, and it may be eliminated.
