25c6cec2a2 Expand the comment on getOpenFileSlice a bit for more details and consistency

70c7e48545 Split getOpenFile into getOpenFile and getOpenFileSlice.
The main observation is that we never need both the filesize and the map size.
When mapping a slice of a file, it doesn't make sense to request a null
terminator and that would be the only case where the filesize would be used.

There are other cleanups that should be done in this area:

* A client should not have to pass the size (even an explicit -1) to say if
  it wants a null terminator or not, so we should probably swap the argument
  order.
* The default should be to not require a null terminator. Very few clients
  require this, but many end up asking for it just because it is the default.

Another 16 testing cases failed and they are disabled with

A total of 34 cases are disabled with -disable-debug-info-verifier and will be

741e37ed0d MC: mayAffectControlFlow() handling for variadic instructions.
Variadic MC instructions don't note whether the variable operands
are uses or defs, so mayAffectControlFlow() must conservatively
assume they are defs and return true if the PC is in the operand
list.

a2549d3827 [Option] Add inclusion and exclusion flags to option parsing
Summary:
This allows the clang driver to put MSVC compatible options in the same
enumerator space as its normal options but exclude them from normal
option parsing.

Also changes the standard ParseArgs() method to consider unknown
arguments with a leading slash as being inputs rather than flags.

06bd2061fc COFFDumper: Dump data directory entries.
Summary:
Dump optional data directory entries in the PE/COFF header, so that
we can test the output of LLD linker. This patch updates the test binary
file, but the source of the binary is the same. I just re-linked the file.
I don't know how the previous file was linked, but the previous file did
not have any data directory entries for some reason.

431b0a7646 [Support] Beef up and expose the response file parsing in llvm::cl
The plan is to use it for clang and lld.

Major behavior changes:
- We can now parse UTF-16 files that have a byte order mark.
- PR16209: Don't drop backslashes on the floor if they don't escape
  anything.

The actual parsing loop was based on code from Clang's driver.cpp,
although it's been rewritten to track its state with control flow rather
than state variables.

60f18ad8a5 Fix a regression I introduced back in r178147.
We don't want cast and dyn_cast to work on temporaries. They don't extend
lifetime like a direct bind to a reference would, so they can introduce
hard to find bugs.

I added tests to make sure we don't regress this. Thanks to Eli Friedman for
noticing this and for his suggestions on how to test it.
