Bill Wendling c2d55b6e50 Add an ivar that maps a landing pad's EH symbol to the call sites that may jump 
to the landing pad. This will be used by the back-end to generate the jump
tables for dispatching the arriving longjmp in sjlj eh.

Evan Cheng bbf3b0de8b Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc. 
There is still a bit more refactoring left to do in Targets. But we are now very
close to fixing all the layering issues in MC.

Evan Cheng 76792992d6 Add MCObjectFileInfo and sink the MCSections initialization code from 
TargetLoweringObjectFileImpl down to MCObjectFileInfo.

TargetAsmInfo is done to one last method. It's *almost* gone!

Bill Wendling 353404d924 Move the compact encoding from the target-specific library to the code-gen 
library.

Evan Cheng d60fa58ba1 Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo down 
to MCRegisterInfo. Also initialize the mapping at construction time.

This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step
towards fixing the layering violation.

Rafael Espindola 56eb741237 Initial support for the cfi directives. This is just enough to get 
f:
        .cfi_startproc
        nop
        .cfi_endproc

assembled (on ELF).

Michael J. Spencer 83ce5f181f CodeGen-Windows: Only emit _fltused if a VarArg function is called with floating point args. 
This should be the minimum set of functions that could possibly need it.

Owen Anderson 6c18d1aac0 Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which 
must be called in the pass's constructor.  This function uses static dependency declarations to recursively initialize
the pass's dependencies.

Clients that only create passes through the createFooPass() APIs will require no changes.  Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.

I have tested this with all standard configurations of clang and llvm-gcc on Darwin.  It is possible that there are problems
with the static dependencies that will only be visible with non-standard options.  If you encounter any crash in pass
registration/creation, please send the testcase to me directly.

Owen Anderson 755aceb5d0 Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static 
ID member as the sole unique type identifier.  Clean up APIs related to this change.

Dan Gohman 1e936277c3 Revert r108369, sorting llvm.dbg.declare information by source position, 
since it doesn't work for front-ends which don't emit column information
(which includes llvm-gcc in its present configuration), and doesn't
work for clang for K&R style variables where the variables are declared
in a different order from the parameter list.

Instead, make a separate pass through the instructions to collect the
llvm.dbg.declare instructions in order. This ensures that the debug
information for variables is emitted in this order.

Dan Gohman f10cd5c6cb Make the order in which variables are described in debug information 
independent of the order that isel happens to visit the dbg_declare
intrinsics. This fixes a bug in which the formal arguments were
being printed in reverse order, now that fast isel is going bottom up.
