Bruno Cardoso Lopes 9fc6b8be03 - Move all MOVSS and MOVSD patterns close to their definitions 
- Duplicate some store patterns to their AVX forms!
- Catched a bug while restricting the patterns subtarget, fix it
  and update a testcase to check it properly

Eli Friedman 3781a36238 Change err_pp_file_not_found back to an Error; when it's a Warning, we suppress it in system headers. And it is not a good idea to suppress it in system headers. (This was originally changed in r134996 to implement -MG.) 
Fixes <rdar://10041960>.  And also brings down the number of warnings without a flag by one :)

Rafael Espindola a45c20b049 Remove the old tail duplication pass. It is not used and is unable to update 
ssa, so it has to be run really early in the pipeline. Any replacement
should probably use the SSAUpdater.

Douglas Gregor 86325ad2b5 Allow C99 hexfloats in C++0x mode. This change resolves the standards 
collision between C99 hexfloats and C++0x user-defined literals by
giving C99 hexfloats precedence. Also, warning about user-defined
literals that conflict with hexfloats and those that have names that
are reserved by the implementation. Fixes <rdar://problem/9940194>.

Jeffrey Yasskin 065c35726f Fix C++0x narrowing errors when char is unsigned. 
In the case of EDInstInfo, this would actually cause a bug when -1 became 255

Douglas Gregor 05ef93158d When writing out the entries in a lookup table for a DeclContext, make

Sebastian Redl 22653bac1a Declare and define implicit move constructor and assignment operator. 
This makes the code duplication of implicit special member handling even worse,
but the cleanup will have to come later. For now, this works.
Follow-up with tests for explicit defaulting and enabling the __has_feature
flag to come.

Rafael Espindola 94d3253626 Adds support for variable sized allocas. For a variable sized alloca, 
code is inserted to first check if the current stacklet has enough
space. If so, space is allocated by simply decrementing the stack
pointer. Otherwise a runtime routine (__morestack_allocate_stack_space
in libgcc) is called which allocates the required memory from the
heap.

Argyrios Kyrtzidis d3497db59b In ASTWriter::WriteDeclContextVisibleBlock, don't write empty lookups. 
Empty lookups can occur in the DeclContext map when we are chaining PCHs, where
the empty lookup indicates that we already looked in ExternalASTSource.

Rafael Espindola 3353017668 Adds a SelectionDAG node X86SegAlloca which will be custom lowered 
from DYNAMIC_STACKALLOC.

Two new pseudo instructions (SEG_ALLOCA_32 and SEG_ALLOCA_64) which
will match X86SegAlloca (based on word size) are also added.  They
will be custom emitted to inject the actual stack handling code.

Patch by Sanjoy Das.

Rafael Espindola c21742112b Emit segmented-stack specific code into function prologues for 
X86. Modify the pass added in the previous patch to call this new
code.

This new prologues generated will call a libgcc routine (__morestack)
to allocate more stack space from the heap when required

Evan Cheng e6fba77971 Follow up to r138791. 
Add a instruction flag: hasPostISelHook which tells the pre-RA scheduler to
call a target hook to adjust the instruction. For ARM, this is used to
adjust instructions which may be setting the 's' flag. ADC, SBC, RSB, and RSC
instructions have implicit def of CPSR (required since it now uses CPSR physical
register dependency rather than "glue"). If the carry flag is used, then the
target hook will *fill in* the optional operand with CPSR. Otherwise, the hook
will remove the CPSR implicit def from the MachineInstr.
