regclass to represent this.  Also fixes a couple of bugs.

C++ semantics, eliminating an extension diagnostic that doesn't match
C++ semantics (ordered comparison with NULL) and tightening some
extwarns to errors in C++ to match GCC and maintain conformance in
SFINAE contexts. Fixes <rdar://problem/7941392>.

flag argument to addReg is not the same format as flags attached
to MachineOperand, although both have the same info.  I don't
think this actually mattered; the bootstrap failure did not
reproduce on the next run anyway.

it or not; will have to check with Greg about how he's handling this
now.  Should update it for the final DWARF3 and soon-to-be-released

SimpleRegisterCoalescing::JoinIntervals() uses CoalescerPair to determine if a
copy is coalescable, and in very rare cases it can return true where LHS is not
live - the coalescable copy can come from an alias of the physreg in LHS.

Fixed the Disassemble arguments so you can't specify start address or name in multiple ways.
Fixed the command line input so you can specify the filename without "-f" even if you use other options.

Fix string concatenation to treat escapes in concatenated strings that
are wide because of other string chunks to process the escapes as wide
themselves.  Before we would warn about and miscompile the attached testcase.

This fixes rdar://8040728 - miscompile + warning: hex escape sequence out of range

Currently, all AST consumers are located in the Frontend library,
meaning that in a shared library configuration, Frontend has a
dependency on Rewrite, Checker and CodeGen.  This is suboptimal for
clients which only wish to make use of the frontend.  CodeGen in
particular introduces a large number of unwanted dependencies.

This patch breaks the dependency by moving all AST consumers with
dependencies on Rewrite, Checker and/or CodeGen to their respective
libraries.  The patch therefore introduces dependencies in the other
direction (i.e. from Rewrite, Checker and CodeGen to Frontend).

After applying this patch, Clang builds correctly using CMake and
shared libraries ("cmake -DBUILD_SHARED_LIBS=ON").

N.B. This patch includes file renames which are indicated in the
patch body.

Changes in this revision of the patch:
 - Fixed some copy-paste mistakes in the header files
 - Modified certain aspects of the coding to comply with the LLVM
   Coding Standards

combined to an insert_subreg, i.e., where the destination register is larger
than the source.  We need to check that the subregs can be composed for that
case in a symmetrical way to the case when the destination is smaller.

Early clobbers defining a virtual register were first alocated to a physreg and
then processed as a physreg EC, spilling the virtreg.

This fixes PR7382.

Given a copy instruction, CoalescerPair can determine which registers to
coalesce in order to eliminate the copy. It deals with all the subreg fun to
determine a tuple (DstReg, SrcReg, SubIdx) such that:

- SrcReg is a virtual register that will disappear after coalescing.
- DstReg is a virtual or physical register whose live range will be extended.
- SubIdx is 0 when DstReg is a physical register.
- SrcReg can be joined with DstReg:SubIdx.

CoalescerPair::isCoalescable() determines if another copy instruction is
compatible with the same tuple. This fixes some NEON miscompilations where
shuffles are getting coalesced as if they were copies.

The CoalescerPair class will replace a lot of the spaghetti logic in JoinCopy
later.
