Explicitly zero out parts of a vector which are required to be zero by the algorithm in LowerUINT_TO_FP_i32.  This only has a substantial effect on the generated code when the input is extracted from a vector register; other ways of loading an i32 do the appropriate zeroing implicitly.  Fixes PR10802.

Apply the same fix for the change in LDR_PRE_IMM/LDRB_PRE_IMM operand encodings to the load-store optimizer that I applied to the instruction selector in r138758.  Fixes ary3 from the nightly test suite.

addrmode_imm12 and addrmode2_offset encode their immediate values differently.  Update the manual instruction selection code that was encoding them the addrmode2 way even though LDR_PRE_IMM/LDRB_PRE_IMM had switched to addrmode_imm12.  Should fix a number of nightly test failures.

Optimize chained bitcasts of the form A->B->A.
Undo r138722 and change isEliminableCastPair to allow this case.

The APFloat "Zero" test was actually calling the
APFloat(const fltSemantics &, integerPart) constructor, and EXPECT_EQ was
treating 0 and -0 as equal.

Add support for parsing #-0 on non-memory-operand immediate values, and add a testcase that necessitates it.

qualification of a type doesn't affect whether a conversion is a narrowing
conversion.
This doesn't work in template cases because SubstTemplateTypeParmType gets in
the way.

[analyzer] Introduce a new callback for checkers, printState, to be used for debug-printing the contents of a ProgramState.

Unlike the other callbacks, this one is a simple virtual method, since it is only to be used for debugging.

This new callback replaces the old ProgramState::Printer interface, and allows us to move the printing of refcount bindings from CFRefCount to RetainReleaseChecker.
