bb705e230a Rename ScalarEvolution::deleteInstructionFromRecords to
deleteValueFromRecords and loosen the types to all it to accept
Value* instead of just Instruction*, since this is what
ScalarEvolution uses internally anyway. This allows more flexibility
for future uses.

485cb57eab Pass a SelectionDAG into SDNode::dump everywhere it's used, in prepration
for needing the DAG node to print pre-legalize extended value types, and
to get better debug messages with target-specific nodes.

dc858f6498 Refactor GVNPRE to use a much smart method of uniquing value sets, and centralize a lot of the value numbering information. No functionality change.

b60d8a92c9 Replace M_REMATERIALIZIBLE and the newly-added isOtherReMaterializableLoad
with a general target hook to identify rematerializable instructions. Some
instructions are only rematerializable with specific operands, such as loads
from constant pools, while others are always rematerializable. This hook
allows both to be identified as being rematerializable with the same
mechanism.

5db3ad4b32 In SCEVAddExpr::get, skip over any cast operands before looking for nested
add operands after constant operands. The recent change to recognize
sign-extend expressions caused this to be exposed more often.

94f3474832 Revert patch. It regresses:
define double @test2(i64 %A) {
   %B = bitcast i64 %A to double
   ret double %B
}

$ llvm-as < t.ll | llc -march=x86-64

before:

         .align  4
         .globl  _test2
_test2:
         movd %rdi, %xmm0
         ret

after:

_test2:
         subq $8, %rsp
         movq %rdi, (%rsp)
         movsd (%rsp), %xmm0
         addq $8, %rsp

720cfb42c6 Fix PR1517:
Use SmallPtrSet instead of std::vector to eliminate duplicate uses in a
function generated with -gen-function. This prevents the output from having
multiple duplicate declarations of constants and gvals.

1732a41371 Really turn if-converter loose:
1. Consider all possible ifcvt cases at once. No longer restricted to bottom
   up iterative approach.
2. Sort all possible cases based on a cost function. Perform the most profitable
   ones first invalidate others that target the same blocks.
3. Fixed a number of bugs related to block duplication.
