Tilmann Scheller b93960d779 Implement the SVR4 ABI for PowerPC.
Implement LowerFORMAL_ARGUMENTS_SVR4().
Implement LowerCALL_SVR4().
Add support for split arguments.
Implement by value parameter passing for aggregates.
Add support for variable argument lists.
Create the spill area for argument registers of variable argument functions no longer at a fixed offset.
Make sure callee saved registers are spilled to the correct stack offsets.
Change allocation order of non-volatile floating-point registers.
Add VRSAVE to the list of callee-saved registers, add CallConvLowering for vararg calls.
Add support for variable argument calls with Vector arguments.
Add support for VR and VRSAVE save area, improve allocation order for non-volatile vector registers.
Stop creating illegal i8 values in LowerVASTART().
Add memory access width hints.
Make sure to reserve space on the stack for the frame pointer.
When using the SVR4 ABI, reserve r13 for the Small Data Area pointer.
Assure that the frame pointer is spilled to the correct location on the stack.
Some FP registers were not marked as volatile.
Make sure the i64 words from a long double are passed either both in registers or both on the stack.
Only put integer arguments in registers which are not marked with the inreg flag.

Tilmann Scheller aea6059ed4 Add NumFixedArgs attribute to CallSDNode which indicates the number of fixed arguments in a vararg call.
With the SVR4 ABI on PowerPC, vector arguments for vararg calls are passed differently depending on whether they are a fixed or a variable argument. Variable vector arguments always go into memory, fixed vector arguments are put 
into vector registers. If there are no free vector registers available, fixed vector arguments are put on the stack.

The NumFixedArgs attribute allows to decide for an argument in a vararg call whether it belongs to the fixed or variable portion of the parameter list.

Mikhail Glushenkov d6c39ae68c Add --enable-llvmc-dynamic configure option.
Controls whether libCompilerDriver should be loaded dynamically. By default this
is needed only on Win32, to make dynamic plugins work.

Eli Friedman 30bd27bf7d Misc compiler-rt fixes. Clarify neg implementations to show what is
actually happening.  Fix mod implementation so it doesn't get 
optimized to a recursive call.  Make x86-32 non-SSE2 shift 
implementation use shld/shrd instead of emulating it (the only x86 processor
where the emulation might be remotely close to justifiable is the Pentium 4).

Chris Lattner cc64cc9313 add an explicit class for holding llvm::SourceMgr diagnostics and use
it to print them.  This gives us column numbers in the diag line.  Before:

t.s:4: error: unexpected token in argument list
 mov %eax %edx
          ^

now:
t.s:4:11: error: unexpected token in argument list
 mov %eax %edx

Ted Kremenek 06cc0e31b2 Replace guarded calls in RegionStoreManager to
ValueManager::getRegionValueSymbolVal() with unguarded calls to
ValueManager::getRegionValueSymbolValOrUnknown(). This changes centralizes the
decision of what values to symbolicate in SymbolManager rather than having it
scatter in RegionStoreManager.
