5ff60c7364 Re-commit 131172 with fix. MachineInstr identity checks should check dead 
markers. In some cases a register def is dead on one path, but not on
another.

This is passing Clang self-hosting.

25d4fce092 Bugpoint support for miscompilations that result in a crash. 
This change allows bugpoint to pinpoint the "opt" pass and bitcode
segment responsible for a crash caused by miscompilation. At least it
works well for me now, without having to create any custom execution
wrappers.

453a924d29 Give the 'eh.sjlj.dispatchsetup' intrinsic call the value coming from the setjmp 
intrinsic call. This prevents it from being reordered so that it appears
*before* the setjmp intrinsic (thus making it completely useless).

17ae92b2d8 Add support for plugins add passes to the default set of passes. The standard set of passes used by front ends can now be modified by LLVM plugins, without needing to modify any front ends. 
Still to do:

- Allow replacing / removing passes (infrastructure there, just needs an infrastructure exposed)
- Defining sets of passes to be added or removed as a group
- Extending the support to allow user-defined groups of optimisations
- Allow plugins to be specified for loading automatically (e.g. from plugins.conf or some similar mechanism)

92dc58fea6 Use .cfi_sections to put the unwind info in .debug_frame when possible. With 
this clang will use .debug_frame in, for example,
clang -g -c -m32 test.c
This matches gcc's behaviour. It looks like .debug_frame is a bit bigger
than .eh_frame, but has the big advantage of not being allocated.

8346c59e6a Producing a DW_FORM_addr for DW_AT_stmt_list is probably correct, but 
it is both inefficient and unexpected by dwarfdump. Change to
a DW_FORM_data4.

While in here, change the predicate name to reflect that the position
is not really absolute (it is an offset), just that the linker needs a
relocation.

that occur in the testsuite and aren't caught by -std-compile-opts.

e0ec7ed462 Add a SlotIndexes::insertMachineInstrInMaps to insert the instruction after any null indexes. 
This makes a difference if a live interval is referring to a deleted
instruction. It can be important to insert an instruction before or after a
deleted instruction to avoid interference.

2f2c3bf31f Simplify the handling of pcrel relocations on ELF. Now we do the right thing 
for all symbol differences and can drop the old EmitPCRelSymbolValue
method.

can be made non-virtual.
