c0fb316bd3 Add an "alignment" field to the MachineFunction object. It makes more sense to
have the alignment be calculated up front, and have the back-ends obey whatever
alignment is decided upon.

This allows for future work that would allow for precise no-op placement and the
like.

40d13bf382 Removing the HasBuiltinSetjmp flag and associated bits. Flagging the presence
of exception handling builtin sjlj targets in functions turns out not to 
be necessary. Marking the intrinsic implementation in the .td file as 
defining all registers is sufficient to get the context saved properly by 
the containing function.

4bb5e9d1df Add support for GCC compatible builtin setjmp and longjmp intrinsics. This is
a supporting preliminary patch for GCC-compatible SjLJ exception handling. Note that these intrinsics are not designed to be invoked directly by the user, but
rather used by the front-end as target hooks for exception handling.

f7e9ff1d28 Move duplicated AddLiveIn function from X86 and ARM backends to be a method

the same method in MachineBasicBlock.  Thanks for Anton for suggesting this.

71bb115e1c Reapply r66415, which was reverted in r66426 for
causing a bootstrap failure.  Bootstraps here on
x86-32-linux and x86-64-linux.  Requested by the
author Gabor Greif who says that a bug that might
have been causing the failure has since been fixed.

9a8e64c76f Give sentinel traits the right to determine the policy where the sentinel is kept.
This should result in less indirect memory accesses, less dead writes and tighter code.

f8d2f7429d "Ghostify" embedded sentinels. This is a real win in all cases
because less bytes are allocated and subobject construction is gone.
For reference how it works, see BasicBlock.h.
Btw. it is very assuring to see that somebody has invented
this ilist-embedded sentinel technique before me :-)

9653b21dc2 Fold the useful features of alist and alist_node into ilist, and
a new ilist_node class, and remove them. Unlike alist_node,
ilist_node doesn't attempt to manage storage itself, so it avoids
the associated problems, including being opaque in gdb.

Adjust the Recycler class so that it doesn't depend on alist_node.
Also, change it to use explicit Size and Align parameters, allowing
it to work when the largest-sized node doesn't have the greatest
alignment requirement.

Change MachineInstr's MachineMemOperand list from a pool-backed
alist to a std::list for now.

cd25487258 Pool-allocation for MachineInstrs, MachineBasicBlocks, and
MachineMemOperands. The pools are owned by MachineFunctions.

This drastically reduces the number of calls to malloc/free made
during the "Emit" phase of scheduling, as well as later phases
in CodeGen. Combined with other changes, this speeds up the
"instruction selection" phase of CodeGen by 10% in some cases.

96167aa93c Rename SSARegMap -> MachineRegisterInfo in keeping with the idea
that "machine" classes are used to represent the current state of
the code being compiled.  Given this expanded name, we can start 
moving other stuff into it.  For now, move the UsedPhysRegs and
LiveIn/LoveOuts vectors from MachineFunction into it.

Update all the clients to match.

This also reduces some needless #includes, such as MachineModuleInfo
from MachineFunction.

7f6a73eb5c Added an automatic cast to "std::ostream*" etc. from OStream. We then can
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

7ed816f900 JumpTable support! What this represents is working asm and jit support for

PIC, and less dense forms of jump tables.
