Emit a proper error message when register allocators run out of registers. This can't be just an assertion, users can always write impossible inline assembly. Such an assembly statement should be included in the error message. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131024 91177308-0d34-0410-b5e6-96231b3b80d8 2011-05-06 21:58:30 +00:00			`; RUN: not llc -march x86 -regalloc=fast < %s 2> %t1`
