ea61af7ff2 Hack the hack. If we have a situation where an ASM object is defined but isn't 
reflected in the LLVM IR (as a declare or something), then treat it like a data
object.

N.B. This isn't 100% correct. The ASM parser should supply more information so
that we know what type of object it is, and what attributes it should have.

8ee5b8754f It could come about that we parse the inline ASM before we get a potential 
definition for it. In that case, we want to wait for the potential definition
before we create a symbol for it.

88a497a1a9 Make some headway towards compiling all of LLVM. 
Module-level ASM may contain definitions of functions and globals. However, we
were not telling the linker that these globals had definitions. As far as it was
concerned, they were just declarations.

Attempt to resolve this by inserting module-level ASM functions and globals into
the '_symbol' set so that the linker will know that they have values.

This gets us further towards our goal of compiling LLVM, but it still has
problems when linking libLTO.dylib because of the `-dead_strip' flag that's
passed to the linker.

9782adedd7 reapply the patches reverted in r149470 that reenable ConstantDataArray, 
but with a critical fix to the SelectionDAG code that optimizes copies
from strings into immediate stores: the previous code was stopping reading
string data at the first nul.  Address this by adding a new argument to
llvm::getConstantStringInfo, preserving the behavior before the patch.

2d545fa143 Split Finish into Finish and FinishImpl to have a common place to do end of 
file error checking. Use that to error on an unfinished cfi_startproc.

The error is not nice, but is already better than a segmentation fault.

7d0d3c2d58 Move global variables in TargetMachine into new TargetOptions class. As an API 
change, now you need a TargetOptions object to create a TargetMachine. Clang
patch to follow.

One small functionality change in PTX. PTX had commented out the machine
verifier parts in their copy of printAndVerify. That now calls the version in
LLVMTargetMachine. Users of PTX who need verification disabled should rely on
not passing the command-line flag to enable it.
