Extended Description

The -inline pass creates invalid bytecode from this testcase:

opt -inline hi_res.bc
WARNING: You're attempting to print out a bytecode file.
This is inadvisable as it may cause display problems. If
you REALLY want to taste LLVM bytecode first-hand, you
can force output with the `-f' option.

Cannot take the address of an inline asm!
invoke void asm "rdtsc\0A\09movl %eax, $0\0A\09movl %edx,
$1", "==imr,==imr,{dirflag},{fpsr},{flags},{dx},~{ax}"( i32* null, i32*
null )
to label %.noexc unwind label %cleanup144
Broken module found, compilation aborted!

A winning combination: exceptions AND inline asm! :)

Fixed, patch here:

Testcase here: Transforms/Inline/2007-04-15-InlineEH.ll
