It's sometimes beneficial to emit a testcase with the old style attribute
syntax. Allow someone to do this.

* We only ever specialize these templates with an instantiation of ELFType,
so we don't need a template template.
* Replace LLVM_ELF_COMMA with just passing the individual parameters to the
macro. This requires a second macro for when we only have ELFT, but that
is still a small win.

unable to handle cases such as __asm mov eax, 8*-8.
This patch also attempts to simplify the state machine. Further, the error
reporting has been improved. Test cases included, but more will be added to
the clang side shortly.

for the sdiv/srem/udiv/urem bitcode instructions. This is done for the i8,
i16, and i32 types, as well as i64 for the x86_64 target.

PR15000 has a testcase where the time to compile was bordering on 30s. When I
dropped the limit value to 100, it became a much more managable 6s. The compile
time seems to increase in a roughly linear fashion based on increasing the limit
value. (See the runtimes below.)
So, let's lower the limit to 100 so that they can get a more reasonable compile
time.

The reference manual defines only 5 permitted values for the immediate field of the "hint" instruction:
1. nop (imm == 0)
2. yield (imm == 1)
3. wfe (imm == 2)
4. wfi (imm == 3)
5. sev (imm == 4)
Therefore, restrict the permitted values for the "hint" instruction to 0 through 4.

GCC complains: Core.cpp:1449:27: warning: overflow in implicit constant conversion [-Woverflow]
I'm not sure if that's really a problem here, but using the enum type is better
style anyways.

A couple of recently introduced conditional branch patterns
also need to be marked as isCodeGenOnly since they cannot
be handled by the asm parser.

This patch allows the Mips assembler to parse and emit nested
expressions as instruction operands. It also extends the
expansion of memory instructions when an offset is given as
an expression.

If a switch instruction has a case for every possible value of its type,
with the same successor, SimplifyCFG would replace it with an icmp ult,
but the computation of the bound overflows in that case, which inverts
the test.

These are aliases for VACGT and VACGE, respectively, with the source
