This undoes the change made in r258163. The assertion fails if `Ptr` is of a
vector type. The previous code doesn't look completely correct either, so I'll
investigate this more.

Do not emit profile arc files and note files for module and skeleton
CU's.
Our users report seeing unexpected *.gcda and *.gcno files in their
projects when using gcov-style profiling with modules or frameworks.
The unwanted files come from these modules. This is not very helpful
for end-users. Further, we've seen reports of instrumented programs
crashing while writing these files out (due to I/O failures).

This change attempts to produce vectorized integer expressions in bit widths
that are narrower than their scalar counterparts. The need for demotion arises
especially on architectures in which the small integer types (e.g., i8 and i16)
are not legal for scalar operations but can still be used in vectors. Like
similar work done within the loop vectorizer, we rely on InstCombine to perform
the actual type-shrinking. We use the DemandedBits analysis and
ComputeNumSignBits from ValueTracking to determine the minimum required bit
width of an expression.

There's an overloading of the "movsd" and "cmpsd" instructions, e.g. movsd can be either "Move Data from String to String" or "Move or Merge Scalar Double-Precision Floating-Point Value".
The former should produce warnings when parsing a memory operand that is not ESI/EDI, but the latter should not.
Fixed the code to produce warnings only after making sure we're dealing with the first case.
Expanded the tests of the produced warnings + fixed RUN line of the test so that it would check both stdout and stderr

Code for handling TLS relocations was moved out scanRelocs() to new function handleTlsRelocations().
That is because scanRelocs already too large to put more TLS code into it.

Summary:
The previous form, taking opcode and type, is moved to an internal
helper and the new form, taking an instruction, is a wrapper around this
helper.
Although this is a slight cleanup on its own, the main motivation is to
refactor the constant folding API to ease migration to opaque pointers.
This will be follow-up work.

Some MIPS relocation (for now R_MIPS_GOT16) requires creation of GOT
entries for symbol not included in the dynamic symbol table. They are
local symbols and non-local symbols with 'local' visibility. Local GOT
entries occupy continuous block between GOT header and regular GOT
entries.
The patch adds initial support for handling local GOT entries. The main
problem is allocating local GOT entries for local symbols. Such entries
should be initialized by high 16-bit of the symbol value. In ideal world
there should be no duplicated entries with the same values. But at the
moment of the `Writer::scanRelocs` call we do not know a value of the
symbol. In this patch we create new local GOT entry for each relocation
against local symbol, though we can exhaust GOT quickly. That needs to
be optimized later. When we calculate relocation we know a final symbol
value and request local GOT entry index. To do that we maintain map
between addresses and local GOT entry indexes. If we start to calculate
relocations in parallel we will have to serialize access to this map.

set the triple's "vendor" field to Apple.
We don't want to assume a vendor of Apple for all Mach-O files -
this breaks x86_64 EFI debugging where they put non-Apple binaries
in a Mach-O format for ease of handling.
But on armv7, Apple's ABI always uses r7 as the frame pointer
register; if we don't set the Vendor field to Apple, we can pick
up a generic armv7 ABI where the fp is r11 (or r7 for thumb) which
breaks backtracing altogether.
Greg is reluctant for us to make any assumptions about the Vendor
here, but we'll see how this shakes out. It's such a big problem
on armv7 if we don't know this is using the Apple ABI that it's worth
trying this approach.

the library names/paths.

On Mac OS X, this was working just fine in debug builds (presumably, because the right value ended up being at the right location for the variadic ABI), but not in Release builds
As a result, we were seeing failures with commands that set their own immediate output stream - only in Release builds, which always makes for a fun little investigation
I have removed those fcntl() calls and replaced them with dup() calls. This fixes the issue in both Debug and Release builds
