Use reserve.

SelectionDAG::allnodes_size is linear, but that doesn't appear to
outweigh the benefit of reducing heap traffic. If it does become a
problem, we should teach SelectionDAG to keep a count of how many
nodes are live, because there are several other places where that
information would be useful as well.

Rename ISD::LOCATION to ISD::DBG_STOPPOINT to better reflect its
purpose, and give it a custom SDNode subclass so that it doesn't
need to have line number, column number, filename string, and
directory string, all existing as individual SDNodes to be the
operands.

This was the only user of ISD::STRING, StringSDNode, etc., so
remove those and some associated code.

This makes stop-points considerably easier to read in
-view-legalize-dags output, and reduces overhead (creating new
nodes and copying std::strings into them) on code containing
debugging information.

Correct the allocation size for CCState's UsedRegs member, which

Revert the SelectionDAG optimization that makes
it impossible to create a MERGE_VALUES node with
only one result: sometimes it is useful to be able
to create a node with only one result out of one of
the results of a node with more than one result, for
example because the new node will eventually be used
to replace a one-result node using ReplaceAllUsesWith,
cf X86TargetLowering::ExpandFP_TO_SINT.  On the other
hand, most users of MERGE_VALUES don't need this and
for them the optimization was valuable.  So add a new
utility method getMergeValues for creating MERGE_VALUES
nodes which by default performs the optimization.
Change almost everywhere to use getMergeValues (and
tidy some stuff up at the same time).

Don't perform expensive queries checking for super and sub registers when we know that there aren't any.
This speed up LiveVariables on instcombine at -O0 -g from 0.3855s to 0.3503s.  Look for more improvements in this area soon!

- Remove a use of std::vector.
- Make sure that we're not recalculating the size of a vector
  that never changes.

Refactor the DebugInfoDesc stuff out of the MachineModuleInfo file. Clean up
some uses of std::vector, where it's return std::vector by value. Yuck!

allow updating the MPM, so that you can use one FunctionPAssManager with
multiple ModuleProviders, e.g. with the JIT.

XFAIL for now.

Update VS project files.  The clang executable now depends on the LLVM Analysis library.

Use a DenseMap instead of an std::map for mangled name lookup.  This is
improves AsmPrinter runtime on instcombine from 0.3920s to 0.3836s.

Don't create a whole new string just to copy the elements into it.

Use the -enable-pre flag so this test doesn't fail.

Cleanup for unitialized types. Patch by Jean-Daniel Dupas!

"An improved Mach-O file type detection for sys::IdentifyFileType()
This patch add supports for single architecture mach-o files (the current implementation only support Universal Binary), and solve the signature conflict between java class and Universal Binary magics.

Note that this function will always returned dynamic library for Universal Binaries (like the current implementation) because the binary type is not include in the file header."

Reserve the size we'll need in advance.

Allow for rounding up of stack frame.

Fixes the last x86-64 test failure in compat.exp:
<16 x float> is 64-byte aligned (for some reason),
which gets us into the stack realignment code.  The
computation changing FP-relative offsets to SP-relative
was broken, assiging a spill temp to a location
also used for parameter passing.  This
fixes it by rounding up the stack frame to a multiple
of the largest alignment (I concluded it wasn't fixable
without doing this, but I'm not very sure.)

Move GetConstantStringInfo to lib/Analysis. Remove
string output routine from Constant. Update all
callers. Change debug intrinsic api slightly to
accomodate move of routine, these now return values
instead of strings.

when we know the signbit of an input to uint_to_fp is zero,
change it to sint_to_fp on targets where that is cheaper (and
visaversa of course).  This allows us to compile uint_to_fp to:

_test:
movl 4(%esp), %eax
shrl $23, %eax
cvtsi2ss %eax, %xmm0
movl 8(%esp), %eax
movss %xmm0, (%eax)
ret

instead of:

.align 3
LCPI1_0: ##  double
.long 0 ## double least significant word 4.5036e+15
.long 1127219200 ## double most significant word 4.5036e+15
.text
.align 4,0x90
.globl _test
_test:
subl $12, %esp
movl 16(%esp), %eax
shrl $23, %eax
movl %eax, (%esp)
movl $1127219200, 4(%esp)
movsd (%esp), %xmm0
subsd LCPI1_0, %xmm0
cvtsd2ss %xmm0, %xmm0
movl 20(%esp), %eax
movss %xmm0, (%eax)
addl $12, %esp

Remember which MachineOperand we were processing, so we don't have to scan the list to find it again later.
This speeds up live intervals from 0.37s to 0.30s on instcombine.
