[LCG] Stop playing fast and loose with reference members and assignment.
It doesn't work. I'm still cleaning up all the places where I blindly
followed this pattern. There are more to come in this code too.

As a benefit, this lets the default copy and move operations Just Work.

Fixing a compile error in debug versions of MSVC. It seems that the range-based for loop is confused by the DEBUG macro expansion unless a compound statement is used.

[mips] Emit '.set nomicromips' before a function's entry label
if not in micromips mode.

The test (elf_st_other.ll) was renamed as the name and description didn't
make sense as the test wasn't checking any symbol table entry.

ARM64: use the integrated assembler on ELF.

ARM64: use 32-bit moves for constants where possible.

If we know that a particular 64-bit constant has all high bits zero, then we
can rely on the fact that 32-bit ARM64 instructions automatically zero out the
high bits of an x-register. This gives the expansion logic less constraints to
satisfy and so sometimes allows it to pick better sequences.

Came up while porting test/CodeGen/AArch64/movw-consts.ll: this will allow a
32-bit MOVN to be used in @test8 soon.

AArch64/ARM64: port across stub handling for ELF C++ exceptions.

The most important part here is that we should actuall emit the stubs we refer
to in the exception table, but as a side issue this uses more sensible & GCC
compatible representations for some of the bits of information.
