This fixes PR37293.
We can have scheduling classes with no write latency entries, that still consume
processor resources. We don't want to treat those instructions as zero-latency
instructions; they still have to be issued to the underlying pipelines, so they
still consume resource cycles.
This is likely to be a regression which I have accidentally introduced at
revision 330807. Now, if an instruction has a non-empty set of write processor
resources, we conservatively treat it as a normal (i.e. non zero-latency)
instruction.

See r331124 for how I made a list of files missing the include.
I then ran this Python script:
for f in open('filelist.txt'):
f = f.strip()
fl = open(f).readlines()
found = False
for i in xrange(len(fl)):
p = '#include "llvm/'
if not fl[i].startswith(p):
continue
if fl[i][len(p):] > 'Config':
fl.insert(i, '#include "llvm/Config/llvm-config.h"\n')
found = True
break
if not found:
print 'not found', f
else:
open(f, 'w').write(''.join(fl))
and then looked through everything with `svn diff | diffstat -l | xargs -n 1000 gvim -p`
and tried to fix include ordering and whatnot.
No intended behavior change.

LLVM_ON_WIN32 is set exactly with MSVC and MinGW (but not Cygwin) in
HandleLLVMOptions.cmake, which is where _WIN32 defined too. Just use the
default macro instead of a reinvented one.
See thread "Replacing LLVM_ON_WIN32 with just _WIN32" on llvm-dev and cfe-dev.
No intended behavior change.
This moves over all uses of the macro, but doesn't remove the definition
of it in (llvm-)config.h yet.

Summary: Add bindings to create import declarations for modules, functions, types, and other entities. This wraps the conveniences available in the existing DIBuilder API, but these seem C++-specific.

With this patch, options to add/tweak views are all grouped together in the
-help output.
The new "View Options" category looks like this:
```
View Options:
-dispatch-stats - Print dispatch statistics
-instruction-info - Print the instruction info view
-instruction-tables - Print instruction tables
-register-file-stats - Print register file statistics
-resource-pressure - Print the resource pressure view
-retire-stats - Print retire control unit statistics
-scheduler-stats - Print scheduler statistics
-timeline - Print the timeline view
-timeline-max-cycles=<uint> - Maximum number of cycles in the timeline view. Defaults to 80 cycles
-timeline-max-iterations=<uint> - Maximum number of iterations to print in timeline view
```

Method BugDriver::performFinalCleanups(...) would delete Module object
it worked on, which was also deleted by its caller
(e.g. TestCodeGenerator(...)). Changed the code to avoid double delete
and make Module ownership slightly clearer.

The instruction printer used by llvm-mca to generate the performance report now
defaults the output assembly format to the format used for the input assembly
file.
On x86, the asm format can be either AT&T or Intel, depending on the
presence/absence of directive `.intel_syntax`.
Users can still specify a different assembly dialect with the command line flag
-output-asm-variant=<uint>.

It used to symlink dsymutil to llvm-dsymutil, but after r327790 llvm's dsymutil
binary is now called dsymutil without prefix.
r327792 then reversed the direction of the symlink if
LLVM_INSTALL_CCTOOLS_SYMLINKS was set, but that looks like a buildfix and not
like something anyone should need.

Zero latency instructions are now scheduled the same way as other instructions.
Before this patch, there was a specialzed code path for those instructions.
All scheduler events are now generated from method `scheduleInstruction()` and
from method `cycleEvent()`. This will make easier to implement a "execution
stage", and let that stage publish all the scheduler events.
No functional change intended.

Summary:
`llvm-bcanalyzer` prints out the stream type of the file it is
analyzing. If the file begins with the LLVM IR magic number, it reports
a stream type of "LLVM IR". However, any other bitstream format is
reported as "unknown".
Add some checks for two other common bitstream formats: Clang AST
files, which begin with 'CPCH', and Clang serialized diagnostics, which
begin with 'DIAG'.
