This commit updates calls to the 'get...' methods from the 'MachinePointerInfo'

For NVPTX, try to use 32-bit division instead of 64-bit division when the dividend and divisor

[LowerSwitch] Fix a bug when LowerSwitch deletes the default block
Summary: LowerSwitch crashed with the attached test case after deleting the default block. This happened because the current implementation of deleting dead blocks is wrong. After the default block being deleted, it contains no instruction or terminator, and it should no be traversed anymore. However, since the iterator is advanced before processSwitchInst() function is executed, the block advanced to could be deleted inside processSwitchInst(). The deleted block would then be visited next and crash dyn_cast<SwitchInst>(Cur->getTerminator()) because Cur->getTerminator() returns a nullptr. This patch fixes this problem by recording dead default blocks into a list, and delete them after all processSwitchInst() has been done. It still possible to visit dead default blocks and waste time process them. But it is a compile time issue, and I plan to have another patch to add support to skip dead blocks.

[RegionInfo] Verify getRegionFor
Summary:
Check the contents of BBtoRegion during analysis verification. It only takes place if -verify-region-info is passed or LLVM is compiled with XDEBUG.
RegionBase<Tr>::verifyRegion() also checks the RegionInfoBase<Tr>::VerifyRegionInfo flag, which is redundant, but verifyRegion() is public API and might be invoked from other sites. In order to avoid behavioral change, this check is not removed. In any case, no region will be verified unless VerifyRegionInfo is set.

Add new ISD nodes: ISD::FMINNAN and ISD::FMAXNAN
The intention of these is to be a corollary to ISD::FMINNUM/FMAXNUM,
differing only on how NaNs are treated. FMINNUM returns the non-NaN
input (when given one NaN and one non-NaN), FMINNAN returns the NaN
input instead.
This patch includes support for scalarizing, widening and splitting
vectors, but not expansion or softening. The reason is that these
should never be needed - FMINNAN nodes are only going to be created
in one place (SDAGBuilder::visitSelect) and there we'll check if the
node is legal or custom. I could preemptively add expand and soften
code, but I'm fairly opposed to adding code I can't test. It's bad
enough I can't create tests with this patch, but at least this code
will be exercised by the ARM and AArch64 backends fairly shortly.

C minnum() is defined to return the non-NaN operand in this case, but

Summary:
This patch remaps the assembly idiom 'move' to 'or' instead of 'daddu' or
'addu'. The use of addu/daddu instead of or as move was highlighted as a
performance issue during the analysis of a recent 64bit design. Originally
move was encoded as 'or' by binutils but was changed for the r10k cpu family
due to their pipeline which had 2 arithmetic units and a single logical unit,
and so could issue multiple (d)addu based moves at the same time but only 1
logical move.
This patch preserves the disassembly behaviour so that disassembling a old style

general, but only when the stack adjustment immediately follows a call - which

That allows taking a short-cut when trying to find a free register to pop into,
instead of a full-blown liveness check. If the adjustment immediately follows a
