This works around a crash where malloc reused the memory of an erased BB for a
new BB leaving old cleanup information pointing at the new block.

VLA restrictions so that one can use VLAs in templates (even
accidentally), but not as part of a non-type template parameter (which
would be very bad).

llvm-mc: Use EmitIntValue where possible, which makes the API calls from the AsmParser and CodeGen line up better.

MC/X86: Subdivide immediates a bit more, so that we properly recognize immediates based on the width of the target instruction. For example:
  addw $0xFFFF, %ax
should match the same as
  addw $-1, %ax
but we used to match it to the longer encoding.

in several important ways:

  - VLAs of non-POD types are not permitted.
  - VLAs cannot be used in conjunction with C++ templates.

These restrictions are intended to keep VLAs out of the parts of the
C++ type system where they cause the most trouble. Fixes PR5678 and
<rdar://problem/8013618>.

temporaries. There are actually several interrelated fixes here:

  - When converting an object to a base class, it's only an lvalue
  cast when the original object was an lvalue and we aren't casting
  pointer-to-derived to pointer-to-base. Previously, we were
  misclassifying derived-to-base casts of class rvalues as lvalues,
  causing various oddities (including problems with reference binding
  not extending the lifetimes of some temporaries).

  - Teach the code for emitting a reference binding how to look
  through no-op casts and parentheses directly, since
  Expr::IgnoreParenNoOpCasts is just plain wrong for this. Also, make
  sure that we properly look through multiple levels of indirection
  from the temporary object, but destroy the actual temporary object;
  this fixes the reference-binding issue mentioned above.

  - Teach Objective-C message sends to bind the result as a temporary
    when needed. This is actually John's change, but it triggered the
    reference-binding problem above, so it's included here. Now John
    can actually test his return-slot improvements.

short name of the tool in use, instead of the name of the action that created
the command. The practical impact is we now get:
  clang: error: clang frontend command failed due to signal 6 (use -v to see invocation)
instead of:
  clang: error: assembler command failed due to signal 6 (use -v to see invocation)
when clang crashes on a job that uses the integrated assembler.
