c98092e28d Use raw_pwrite_stream in the object writer/streamer.
The ELF object writer will take advantage of that in the next commit.

script. This is in preparation for changes to lots of include lines.

3f6dea4864 ARM: fail less catastrophically on invalid Windows input
Windows supports a restricted set of relocations (compared to ARM ELF).  In some
cases, we may end up generating an unsupported relocation.  This can occur with
bad input to the assembler in particular (the frontend should never generate
code that cannot be compiled).  Generate an error rather than just aborting.

The change in the API is driven by the desire to provide a slightly more helpful
message for debugging purposes.

cba7ac7bda MC: correct IMAGE_REL_ARM_MOV32T relocation emission
This corrects the emission of IMAGE_REL_ARM_MOV32T relocations.  Previously, we
were avoiding the high portion of the relocation too early.  If there was a
section-relative relocation with an offset greater than 16-bits (65535), you
would end up truncating the high order bits of the offset.  Allow the current
relocation representation to flow through out the MC layer to the object writer.
Use the new ability to restrict recorded relocations to avoid emitting the
relocation into the final object.

dade1d5db5 ARM: support FK_SecRel_2 relocations on WoA
This adds FK_SecRel_2 relocation support to ARM.  This enables the building of
object files for armv7-windows-msvc which enables CodeView line tables for
debugging as opposed to armv7-windows-itanium which currently uses DWARF.

a7321a6e53 MC: support FK_SecRel_4 for Windows on ARM
Add handling for FK_SecRel_4 (4-byte section relative relocations).  These are
used by the generation of DWARF debug information (the abbrevations use section
relative relocations).  This will also be used in generation of CodeView line
tables.

f090afddb4 ARM: MSVC does not support = default
Explicitly "implement" the destructor as MSVC does not support defaulted methods
yet.

2d0d7fd085 Add WoA object file emission support
Introduce support for WoA PE/COFF object file emission from LLVM.  Add the new
target specific PE/COFF Streamer (ARMWinCOFFStreamer) that handles the ARM
specific behaviour of PE/COFF object emission.  ARM exception information is not
yet emitted and is a TODO item.

The ARM specific object writer (ARMWinCOFFObjectWriter) handles the ARM specific
relocation handling in conjunction with the WinCOFFObjectWriter in the MC layer.
The MC layer needs to be updated to deal with the relocation adjustments.
Branch relocations are adjusted by 4 bytes (unlikely their ELF counterparts).

Minor tweaks to switch multiple conditional checks into equivalent switch
statements.  The ObjectFileInfo is updated to relax the object file setup for
Windows COFF.  Move the architecture checks into an assertion.  Windows COFF is
currently only supported on x86, x86_64, and ARM (thumb).  Rather than
defaulting to ELF, we will refuse to generate an object file.  This is better
though as you do not get an (arbitrary) object file which is different from the
request.
