Rafael Espindola 557679f42b Add a ENABLE_X86_RELAX_RELOCATIONS cmake option.
This corresponds to binutils' --enable-x86-relax-relocations.

Reid Kleckner 0abaef604d Use the same tag type across all PointerLikeTypeTraits specializations
Works around a bug (PR28216) in Clang's MS mangling of templates with
partial specializations.

This mismatch was introduced in about six months ago in r256656.

Rafael Espindola 0d34826218 Simplify PICStyles.
The main difference is that StubDynamicNoPIC is gone. The
dynamic-no-pic mode as the name implies is simply not pic. It is just
conservative about what it assumes to be dso local.

George Burgess IV 87b2e41416 [CFLAA] Add interprocedural function summaries.
This patch adds function summaries, so that we don't need to recompute
various properties about function parameters/return values at each
callsite of a function. It also adds many interprocedural tests for
CFLAA.

Patch by Jia Chen.

Fix for PR27726 - sitofp i64 to fp128 was loading the merged load i64 to a x87 register preventing legalization for conversion to fp128.

Kevin Enderby eb6d110c1d Add support for Darwin’s 64-bit universal files with 64-bit offsets and sizes for the objects.
Darwin added support in its Xcode 8.0 tools (released in the beta) for universal
files where offsets and sizes for the objects are 64-bits to allow support for
objects contained in universal files to be larger then 4gb.  The change is very
straight forward.  There is a new magic number that differs by one bit, much
like the 64-bit Mach-O files.  Then there is a new structure that follow the
fat_header that has the same layout but with the offset and size fields using
64-bit values instead of 32-bit values.

Aaron Ballman 3dd74b8edb Fix a relatively nasty bug with fs::getPathFromOpenFD() on Windows. The GetFinalPathNameByHandle API does not behave as documented; if given a buffer that has enough space for the path but not the null terminator, the call will return the number of characters required *without* the null terminator (despite being documented otherwise) and it will not set GetLastError(). The result was that this function would return a bogus path and no error. Instead, ensure there is sufficient space for a null terminator (we already strip it off manually for compatibility with older versions of Windows).
