Jason Molenda 956ff0f8bf If we fail to get an armv7em-- disassembler from llvm, skip the
tests and don't mark this as a failure.  This happens when we've
linked against an llvm without the ARM target built in.  Davide
added some cmake conditionals to avoid building this test when the
target was absent from llvm's build, but we're still finding some
bots that manage to get in this situation.

Raphael Isemann b658f1df35 [NFC] Fix compiler warning in TestArmv7Disassembly.cpp
The warning is
    comparison of integers of different signs: 'const int' and 'const unsigned long'
and triggered by
    EXPECT_EQ (num_of_instructions, inst_list.GetSize());
as num_of_instructions is an int in this comparison (and the RHS is size_t).

Jason Molenda 0dfb84ce9b Enable the fp-armv8 disassembler feature when disassembling Cortex-M
code.  This will enable disassembly of the optional subset of
neon that some Cortex cores support.  Add a unit test to check
that a few of these instructions disassemble as expected.
