The previous code would always do 1 or 2 prefix compares;
explicitly only do one.
This speeds up debug -gen-asm-matcher by ~10% (e.g. X86: 40s -> 35s).

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.

Nearly all the changes to this pass have been done while maintaining and
updating other parts of LLVM. LLVM has had another pass, SROA, which
has superseded ScalarReplAggregates for quite some time.

Summary:
This new alias takes a comma separated list of prefixes which allows
'--check-prefix=A --check-prefix=B --check-prefix=C' to be written as
'--check-prefixes=A,B,C'.

When visualizing small vectors in VS2015, show the first few elements in the DisplayString instead of the size. For example, a SmallVector of DeclAccessPair will visualize like
{public typename ...Ts, public typename U}
The visualization in VS2013 remains the same because we continue to include the old visualizer with a lower-than-default priority of MediumLow, and the same SmallVector would continue to be visualized as
{size = 2}

The script now replace '.LCPI888_8' style asm symbols with the {{\.LCPI.*}} re pattern - this helps stop hardcoded symbols in 32-bit x86 tests changing with every edit of the file
Refreshed some tests to demonstrate the new check

- The intended use of this was just in diagnostics, so we shouldn't pay the
cost of reading these all the time.
- This will avoid including the full output of each command in tests which
fail, but the most important use case for this was to gather the output of
the specific command which failed.

Use os.devnull instead of tempfiles when substituting '/dev/null' on
Windows machines. This should make the bots just a bit speedier.
Thanks to Yunzhong Gao for testing this patch on Windows!

looking for it along $PATH. This allows installs of LLVM tools outside of
$PATH to find the symbolizer and produce pretty backtraces if they crash.

- This will cause lit to automatically include the first 1K of data in
redirected output files when a command fails (previously if the command
failed, but the main point of the test was, say, a `FileCheck` later on, then
the log wasn't helpful in showing why the command failed).
