Stephen Wilson 50bd94f961 Have Process::CreateBreakpointSite return a break_id_t instead of a user_id_t. 
Also, update BreakpointLocation::ResolveBreakpointSite to check for invalid
breakpoint ID's using the proper magic constant.

Eric Christopher 24e3aa011a Make more explicit and add some currently disabled error messages for 
stack realignment on ARM.

Also check for function attributes as we do on X86 as well as
make explicit that we're checking can as well as needs in this function.

Jim Grosbach 11013eda5a Add basic support to code-gen the ARM/Thumb2 bit-field insert (BFI) instruction 
and a combine pattern to use it for setting a bit-field to a constant
value. More to come for non-constant stores.

Bill Wendling bf8370ff36 Consider this function: 
void foo() { __builtin_unreachable(); }

It will output the following on Darwin X86:

_func1:
Leh_func_begin0:
        pushq %rbp
Ltmp0:
        movq %rsp, %rbp
Ltmp1:
Leh_func_end0:

This prolog adds a new Call Frame Information (CFI) row to the FDE with an
address that is not within the address range of the code it describes -- part is
equal to the end of the function -- and therefore results in an invalid EH
frame. If we emit a nop in this situation, then the CFI row is now within the
address range.

Tom Care 826e6b4023 Improved false positive rate for the idempotent operations checker and moved it into the default path-sensitive analysis options. 
- Added checks for static local variables, self assigned parameters, and truncating/extending self assignments
- Removed command line option (now default with --analyze)
- Updated test cases to pass with idempotent operation warnings

Dan Gohman 1e936277c3 Revert r108369, sorting llvm.dbg.declare information by source position, 
since it doesn't work for front-ends which don't emit column information
(which includes llvm-gcc in its present configuration), and doesn't
work for clang for K&R style variables where the variables are declared
in a different order from the parameter list.

Instead, make a separate pass through the instructions to collect the
llvm.dbg.declare instructions in order. This ensures that the debug
information for variables is emitted in this order.
