Add a MI->emitError() method that the backend can use to report errors
related to inline assembly. Call it from X86FloatingPoint.cpp when the
constraints are wrong.

This enables proper clang diagnostics from the backend:

$ clang -c pr30848.c
pr30848.c:5:12: error: Inline asm output regs must be last on the x87 stack
  __asm__ ("" : "=u" (d));  /* { dg-error "output regs" } */

Every live range is assigned a cascade number the first time it is
involved in an eviction. As the evictor, it gets a new cascade number.
Every evictee is assigned the same cascade number as the evictor.

Eviction is prohibited if the evictor has a lower assigned cascade
number than the evictee.

This means that assigned cascade numbers are monotonically increasing
with every eviction, yet they are bounded by NextCascade which can only
be incremented by new live ranges. Thus, infinite loops cannot happen,
but eviction cascades can still be triggered by new live ranges as we
want.

Thanks to Andy for explaining this to me.

Especially SBProcess.ReadMemory() and SBProcess.WriteMemory() because the generated autodoc strings
make no sense for Python programmers due to typemap (see lldb.swig).

Make clang behave in a gcc-compatible way in the presence of multiple flags for the same x86 target feature (e.g. -mno-sse -msse).  gcc uses a somewhat unintuitive algorithm here in that the enabled SSE instructions is based on the order of the *last* flag for *each* feature-level, so that "-mno-sse -msse2" only enables SSE2, but "-mno-sse -msse2 -msse" enables all SSE levels.

Issue reported on cfe-dev.

 - type names can now be regular expressions (exact matching is done first, and is faster)
 - integral (and floating) types can be printed as bitfields, i.e. ${var[low-high]} will extract bits low thru high of the value and print them
 - array subscripts are supported, both for arrays and for pointers. the syntax is ${*var[low-high]}, or ${*var[]} to print the whole array (the latter only works for statically sized arrays)
 - summary is now printed by default when a summary string references a variable. if that variable's type has no summary, value is printed instead. to force value, you can use %V as a format specifier
 - basic support for ObjectiveC:
  - ObjectiveC inheritance chains are now walked through
  - %@ can be specified as a summary format, to print the ObjectiveC runtime description for an object
 - some bug fixes

conventional in the rest of Clang's codebase, and closer to the current
style recommendations. It also makes the code more internally consistent
as FD, VD, etc are used frequently for particular decl variables.

 newly introduced Sema::BuildVectorLiteral.
-Make Sema::ActOnCastExpr handle a vector initializer both when the cast'ed expression
 is a ParenListExpr and when it is a ParenExpr.
-Ultimately make Sema::ActOnParenOrParenListExpr independent of what the cast type was.

cast type has no ownership specified, implicitly "transfer" the ownership of the cast'ed type

This currently only works for C++ named casts, C casts to follow.

Break Sema::GetTypeForDeclarator in 2 functions, one for DeclSpec processing and another for the rest.
No functionality change.

Introduce Declarator::ObjCCatchContext, this will result in correct error for 'auto' in obj-c catch.
