d14be3d83c Attempt again to fix buildbot failures: make expected output less specific 
and compile with -mtriple to specify *-apple-darwin targets.

801415706c RangeIsDefinedByCopyFromReg() should check for subreg_to_reg, insert_subreg, 
and extract_subreg as a "copy" that defines a valno.
Also fixes a typo. These two issues prevent a simple subreg coalescing from
happening before.

ec5cb0cdbd Initilize the machine LICM CSE map upon the first time an instruction is hoisted to 
the loop preheader. Add instructions which are already in the preheader block that
may be common expressions of those that are hoisted out. These does get a few more
instructions CSE'ed.

4cf2980e59 improve x86 codegen support for blockaddress. We now compile 
the testcase into:

_test1:                                                     ## @test1
## BB#0:                                                    ## %entry
	leaq	L_test1_bb6(%rip), %rax
	jmpq	*%rax
L_test1_bb:                                                 ## Address Taken
LBB1_1:                                                     ## %bb
	movb	$1, %al
	ret
L_test1_bb6:                                                ## Address Taken
LBB1_2:                                                     ## %bb6
	movb	$2, %al
	ret

Note, it is very very strange that BlockAddressSDNode doesn't carry 
around TargetFlags.  Dan, please fix this.

534d2cb249 Expand 64 bit left shift inline rather than using the libcall. For now, this 
is unconditional. Making it still use the libcall when optimizing for size
would be a good adjustment.

ad6c6a3d33 Fix MachineLICM to use the correct virtual register class when 
unfolding loads for hoisting.  getOpcodeAfterMemoryUnfold returns the
opcode of the original operation without the load, not the load
itself, MachineLICM needs to know the operand index in order to get
the correct register class. Extend getOpcodeAfterMemoryUnfold to
return this information.

d4fadd76da This fixes functions like 
void f (int a1, int a2, int a3, int a4, int a5,...)

In ARMTargetLowering::LowerFormalArguments if the function has 4 or
more regular arguments we used to set VarArgsFrameIndex using an
offset of 0, which is only correct if the function has exactly 4
regular arguments.
