from the LC_DATA_IN_CODE load command. And when disassembling print
the data in code formatted for the kind of data it and not disassemble those
bytes.
I added the format specific functionality to the derived class MachOObjectFile
since these tables only appears in Mach-O object files. This is my first
attempt to modify the libObject stuff so if folks have better suggestions
how to fit this in or suggestions on the implementation please let me know.

The TargetLoweringInfo object is owned by the TargetMachine. In the future, the
TargetMachine object may change, which may also change the TargetLoweringInfo
object.

A user shouldn't care about the internal state, and these methods by
their very nature require asserting a predicate on the internal state.
As such, they cannot be used safely without introducing hidden
long-distance dependencies on the manner of construction of the
BinaryRef.
Use writeAsBinary(raw_ostream &) and writeAsHex(raw_ostream &) if you
need to access the data in a binary or hex format.

This hides the implementation. A future commit will remove the
error-prone getHex() and getBinary() methods.

Previously, yaml2coff.cpp had a writeHexData static helper function to
do this, but it is generally useful functionality.
Also, validate hex strings up-front to avoid running having to handle
errors "deep inside" the yaml2obj code (it also gives better diagnostics
than it used to).

Previously commited @183279 but tests were failing, reverted @183286
It was broken because @183336 was missing, now it's there.

The first symbol on ELF is dummy, but it has a defined content and readelf
normally displays it. With this change llvm-readobj also displays it and we
can check that llvm-mc output is correct according to the standard.

See the comment in yaml2obj.cpp for why this is currently needed.
Eventually we can get rid of this, but for now it is needed in order to
make forward progress with adding ELF support, and should be
straightforward to remove later.
Also, preserve the default of COFF, to avoid breaking existing tests.
This policy can easily be changed later though.

With this patch we use the SectionIndex directly, instead of counting the
number of symbol tables. This saves a DenseMap lookup every time we want to
find which symbol a relocation refers to.
Also simplify based on the fact that there is at most one SHT_SYMTAB and one
SHT_DYNSYM.

Add some generic SchedWrites and assign resources for Swift and Cortex A9.
Reapply of r183257. (Removed empty InstRW for division on swift)

An instruction with less than 3 inputs is trivially a fast immediate shift.
Reapply of 183256, should not have caused the tablegen segfault on linux either.

Don't output data if we are supposed to ignore the record.
Reapply of 183255, I don't think this was causing the tablegen segfault on linux
testers.
