27d6681496 1) Merge entire live intervals instead of parts of them. 
2) Conditionalize temporary insertion if we don't need it.

739e441311 Removed SELECT_CC custom lowering. This is not needed anymore, the SELECT node 
is lowered properly and covers everything LowerSELECT_CC did.
Added method printUnsignedImm in AsmPrinter to print uimm16 operands. This
avoid the ugly instruction by instruction checking in printOperand.
Added a swap instruction present in the allegrex core.
Added two conditional instructions present in the allegrex core : MOVZ and MOVN.
They both allow a more efficient SELECT operation for integers.
Also added SELECT patterns to optimize MOVZ and MOVN usage.
The brcond and setcc patterns were cleaned: redundant and suboptimal patterns
were
removed. The suboptimals were replaced by more efficient ones.
Fixed some instructions that were using immZExt16 instead of immSExt16.

6f83be0c61 When resolving a stub in x86-64 JIT, use a PC-relative branch 
rather than the absolute address if the target is within range.

50dd1d0280 Some fixes for x86-64 JIT. Make it use small code 
model, except for external calls; this makes
addressing modes PC-relative.  Incomplete.

The assertion at the top of Emitter::runOnMachineFunction
was obviously bogus (always true) so I removed it.
If someone knows what the correct test should be to cover
all the various targets, please fix.

e3d920699c Re-enable elimination of unnecessary SUBREG_TO_REG instructions in 
LowerSubregs, and fix an x86-64 isel bug that this exposed.

SUBREG_TO_REG for x86-64 implicit zero extension is only safe for
isel to generate when the source is known to always have zeros in
the high 32 bits. The EXTRACT_SUBREG instruction does not clear
the high 32 bits.

dd947ea3c5 Rewrite JIT handling of GlobalVariables so they 
are allocated in the same buffer as the code,
jump tables, etc.

The default JIT memory manager does not handle buffer
overflow well.  I didn't introduce this and I'm not
attempting to fix it here, but it is more likely to
be hit now since we're putting more stuff in the
buffer.  This affects one test that I know of so far,
MultiSource/Benchmarks/NPB-serial/is.

bbe51362d5 Added support for fp callee saved registers. 
Added fp register clobbering during calls.
Added AsmPrinter support for "fmask", a bitmask that indicates where on the 
stack the fp callee saved registers are.

Fixed the stack frame layout for Mips, now the callee saved regs 
are in the right stack location (a little documentation about how this
stack frame must look like is present in MipsRegisterInfo.cpp).
This was done using the method MipsRegisterInfo::adjustMipsStackFrame
To be more clear, these are examples of what is solves :  

1) FP and RA are also callee saved, and despite they aren't in CSI they 
   must be saved before the fp callee saved registers. 
2) The ABI requires that local varibles are allocated before the callee 
   saved register area, the opposite behavior from the default allocation.
3) CPU and FPU saved register area must be aligned independent of each
   other.
