7e08984661 Small improvement to the use of GetFileType:
* assert that the return value is one of the documented values on msdn.
* on FILE_TYPE_UNKNOWN, check GetLastError.

Unfortunately I can't think of a way to get a FILE_TYPE_UNKNOWN on a test.

c1af8a0511 [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.

106d44afb8 [SystemZ] Generalize RxSBG SRA case
The original code only folded SRA into ROTATE ... SELECTED BITS
if there was no outer shift.  This patch splits out that check

interesting, but this is paving the way for RNSBG support.

f4dabb5510 [SystemZ] Rename and formatting fixes
In hindsight, using "RISBG" for something that can be any type of
R.SBG instruction was a bit confusing, so this renames it to RxSBG.
That might not be the best choice either, since there is an instruction
called RXSBG, but hopefully the lower-case letter stands out enough.

While there I fixed a couple of GNUisms that had crept in --
sorry about that!

b59978aea3 Reapply r186316 with a fix for one bug where the code could walk off the
end of a vector. This was found with ASan. I've had one other report of
a crasher, but thus far been unable to reproduce the crash. It may well
be fixed with this version, and if not I'd like to get more information
from the build bots about what is happening.

See r186316 for the full commit log for the new implementation of the
SROA algorithm.

fdd124178e PPC: Support dynamic allocas with large alignment
Support for dynamic stack alignments in the PPC backend has been unfinished, in
part because it depends on dynamic stack realignment (which I only just
recently implemented fully). Now we can also support dynamic allocas with
higher than the default target stack alignment (16 bytes).

In order to round-up the requested size to the maximum requested alignment, we
need an additional register to hold the rounded-up size. We're already using one
scavenged register to hold the previous stack-pointer value (which needs to be
stored with the signal-safe stdux update), and so when we have dynamic allocas
and a large alignment, we allocate two emergency spill slots for the scavenger.

9e2da8f46a 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.

79a33a00d6 PPC: Add base-pointer support to builtin setjmp/longjmp
First, this changes the base-pointer implementation to remove an unnecessary
complication (and one that is incompatible with how builtin SjLj is
implemented): instead of using r31 as the base pointer when it is not needed as
a frame pointer, now the base pointer will always be r30 when needed.

Second, we introduce another pseudo register, BP, which is used just like the FP
pseudo register to refer to the base register before we know for certain what
register it will be.

Third, we now save BP into the jmp_buf, and restore r30 from that slot in
longjmp.  If the function that called setjmp did not use a base pointer, then
r30 will be overwritten by the setjmp-calling-function's restore code. FP
restoration (which is restored into r31) works the same way.

8a4d277bbd Add an explicit operator bool conversion to DIDescriptor to make
it clear what we want to do. Unfortunately the conversion to
pointer operator fires now instead and chasing down all of the
conversions and making them explicit and handled is a large task
so add a FIXME with it.

d18dd0a7b0 Handle '.' correctly in hex float literal parsing.
There were a couple of different loops that were not handling
'.' correctly in APFloat::convertFromHexadecimalString; these mistakes
could lead to assertion failures and incorrect rounding for overlong
hex float literals.

fc79c747f8 Add FILE_SHARE_WRITE to openFileForRead.
This should fix the windows bots. It looks like the failing tests are of the
form

prog1 > file
prog2 file

and prog2 fails trying to read the file. The best fix would probably be to close
stdout/stderr in prog1, but it was not the intention of 186511 to change this,
so just restore the old behavior for now.

* Easy to produce good errors on windows about trying to use a

* Simplifies the unix version a bit.
