R600: Schedule copy from phys register at beginning of block

It allows regalloc pass to remove them by trivially assigning associated reg

Don't hide the first ELF symbol.

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.

[ELF] Add ELFOSABI_GNU.

ELFOSABI_LINUX is a historical alias for ELFOSABI_GNU according to
<http://www.sco.com/developers/gabi/latest/ch4.eheader.html>.

R600: Add a pass that merge Vector Register

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

Add writeAsBinary(raw_ostream &) method to BinaryRef.

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).

Comment BinaryRef::Data.

Also, state an invariant.

Add BinaryRef binary_size() method.

This avoids making assumptions about the data representation.

Rename BinaryRef::isBinary to more descriptive DataIsHexString.

And add a doxygen comment.

R600: Replace predicate loop with predicate function

Add writeAsHex(raw_ostream &) method to BinaryRef.

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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183352 91177308-0d34-0410-b5e6-96231b3b80d8
Remove error-prone methods of BinaryRef.

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.

Rename operator== parameter to `RHS`.

The previous name `Ref` is overly generic.

Don't cache the TargetLoweringInfo object inside of the FunctionLowering object.

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

Cache the TargetLowering info object as a pointer.

Caching it as a pointer allows us to reset it if the TargetMachine object
changes.
