Change coalescer complexity from N^2 to N logN by changing one letter.
...
Remove ugly hack that aborted the coalescer before using N^2 time.
This affects functions with very complicated live intervals for physical
registers, i.e. functions with thousands of function calls.

Fixed a bug in the IT mask printing where T means the cond bit in the mask
...
matches that of Firstcond[0] and E means otherwise. The Firstcond[0] is also
tagged in the Mask to facilitate Asm printing. The disassembler also depends
on this arrangement. This is similar to what's described in A2.5.2 ITSTATE.
Ran:
utils/lit/lit.py test/CodeGen/ARM test/CodeGen/Thumb test/CodeGen/Thumb2
successfully.

Refines 98745 so that it only contains the patch related to the output of the

This patch removes the impl of printT2AddrModeImm8s4OffsetOperand() from
ARMAsmPrinter.cpp. It is used by disassembler as of now.

Change SCEVNAryExpr's operand array from a SmallVector to a plain

pointer and length, and allocate the arrays in ScalarEvolution's
BumpPtrAllocator, so that they get released when their owning
SCEV gets released. SCEVs are immutable, so they don't need to worry
about operand array resizing. This fixes a memory leak reported
in PR6637.

instructions to help disassembly.
We also changed the output of the addressing modes to omit the '+' from the
assembler syntax #+/-<imm> or +/-<Rm>. See, for example, A8.6.57/58/60.
And modified test cases to not expect '+' in +reg or #+num. For example,

Fix EmitSectionOffset incorrect argument. DwarfDebug is emitting debug info so isEH is always false. This was hiding until now from compilers because of default arguments.

But Chris found it while updating dwarf printer to use MC*.
