[llvm-reduce] Remove module asm

[nikic]

llvm-reduce should try to remove module asm.

[nikic]

This already exists:

llvm-project/llvm/tools/llvm-reduce/deltas/ReduceModuleData.cpp

Lines 25 to 26 in 3d7a3a1

	if (!Program.getModuleInlineAsm().empty() && !O.shouldKeep())
	Program.setModuleInlineAsm("");

I no longer have the test case where the module asm was left over. Closing this for now...
