[Mips Disassembler] Have the DecodeCCRRegisterClass function use the getReg
function to lookup the proper tablegen'ed register enumeration.  Previously,
it was using the encoded value directly.

Fix a crash bug in dumping options with groups

Option groups don't have prefixes.  Option dumping is basically dead
code unless there is something wrong with the option table, so this
isn't an important crasher.

[APFloat] Convert all references to fcNormal to references to isFiniteNonZero().

Currently inside APFloat fcNormal still implies the old definition of Normal
(i.e. isFiniteNonZero) instead of the proper IEEE-754R definition that the
external method isNormal() uses.

This patch prepares for the internal switch inside APFloat by converting all
references that check if a category is fcNormal directly with an indirect call
via isFiniteNonZero().

SLP: Dont erase instructions during vectorization because it prevents the outerloops from iterating over the instructions.

SLP: When searching for vectorization opportunities scan the blocks in post-order because we grow chains upwards.

LoopVectorize: Don't store a reversed value in the vectorized value map

When we store values for reversed induction stores we must not store the
reversed value in the vectorized value map. Another instruction might use this
value.

This fixes 3 test cases of PR16455.

Add a convenience createUniqueDirectory function.

There are a few valid situation where we care about the structure inside a
directory, but not about the directory itself. A simple example is for unit
testing directory traversal.

PathV1 had a function like this, add one to V2 and port existing users of the
created temp file and delete it hack to using it.

Add CXXFLAGS back to the Link command.

This is essentially reverting one piece of 184793 to try to fix one of Apple's

some other solution.
