1bfcd5b981 Add a new emitAlignment method 
llvm-svn: 28072

06ccac43d7 Change the BasicBlockAddrs map to be a vector, indexed by MBB number.

2bf37af52d Several related changes: 
1. Change several methods in the MachineCodeEmitter class to be pure virtual.
2. Suck emitConstantPool/initJumpTableInfo into startFunction, removing them
   from the MachineCodeEmitter interface, and reducing the amount of target-
   specific code.
3. Change the JITEmitter so that it allocates constantpools and jump tables
   *right* next to the functions that they belong to, instead of in a separate
   pool of memory.  This makes all memory for a function be contiguous, and
   means the JITEmitter only tracks one block of memory now.

8054cd3830 Do not make the JIT memory manager manage the memory for globals. Instead 
just have the JIT malloc them.

d100478886 Fix a purely hypothetical problem (for now): emitWord emits in the host 
byte format.  This doesn't work when using the code emitter in a cross target
environment.  Since the code emitter is only really used by the JIT, this
isn't a current problem, but if we ever start emitting .o files, it would be.

055baf5c7b Refactor the machine code emitter interface to pull the pointers for the current 
code emission location into the base class, instead of being in the derived classes.

This change means that low-level methods like emitByte/emitWord now are no longer
virtual (yaay for speed), and we now have a framework to support growable code
segments.  This implements feature request #1 of PR469.

05174045df Extend printBasicBlockLabel a bit so that it can be used to print all 
basic block labels, consolidating the code to do so in one place for each
target.

node can be folded.

e521de4e60 Added X86 SSE2 intrinsics which can be represented as vector_shuffles. This is 
a temporary workaround for the 2-wide vector_shuffle problem (i.e. its mask
would have type v2i32 which is not legal).

7bb910dbe7 Fix the updating of the machine CFG when a PHI node was in a successor of 
the jump table's range check block.  This re-enables 100% dense jump tables
by default on PPC & x86

7ed816f900 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

ec4d1668ef Added a virtual method isVectorClearMaskLegal to TLI. It is similar to 
isShuffleMaskLegal, used to determine if it makes sense to turn a
"vector clear" (e.g. pand V, <0, -1, 0, -1> to a shuffle of the vector and
a zero vector.
