This makes it much easier to debug issues when the logging contains the
name of the SCC. It requires to create a temporary string, but for
logging and debugging uses that seems fine. I've added logic to try to
output all the function names with an elipsis if there are too many.
This was helpful fro me in debugging issues with the new pass manager.

Summary:
This instcombine rule folds away trunc operations that have value available from a prior load or store.
This kind of code can be generated as a result of GVN widening the load or from source code as well.

Recommiting after correcting over-eager Debug Value transfer fixing PR28270.
[DAG] Previously debug values would transfer debuginfo for the selected
start node for a replacement which allows for debug to be dropped.
Push debug value transfer to occur with node/value replacement in
SelectionDAG, remove now extraneous transfers of debug values.
This refixes PR9817 which was being incompletely checked in the
testsuite.

Summary:
SSAT saturates an integer, making sure that its value lies within
an interval [-k, k]. Since the constant is given to SSAT as the
number of bytes set to one, k + 1 must be a power of 2, otherwise
the optimization is not possible. Also, the select_cc must use <
and > respectively so that they define an interval.

Currently isComplete = 1 requires that every instruction must
be described, declared unsupported or marked as having no
scheduling information for a processor.
For some backends such as MIPS, this requirement entails
long regex lists of instructions that are unsupported.
This patch teaches Tablegen to skip over instructions that
are associated with unsupported feature when checking if the
scheduling model is complete.

MCSymbol.h shouldn't pull in MCAssembler.h, just MCFragment.h.
MCLinkerOptimizationHint.h shouldn't need MCMachObjectWriter.h. The
rest is fixing the fallout.

This is a follow-up to r273479. At the time I wrote r273479 I didn't connect the dots that the functions I was adding had to exist somewhere. Turns out, they do. This finishes moving the functions to MachO.h.
Existing MachO fat header tests like test/tools/llvm-readobj/Inputs/macho-universal-archive.x86_64.i386 execute this code.
