Set sub-register <undef> flags more accurately.
When widening an existing <def,reads-undef> operand to a super-register,
it may be necessary to clear the <undef> flag because the wider register
is now read-modify-write through the instruction.
Conversely, it may be necessary to add an <undef> flag when the
coalescer turns a full-register def into a sub-register def, but the
larger register wasn't live before the instruction.
This happens in test/CodeGen/ARM/coalesce-subregs.ll, but the test
is too small for the <undef> flags to affect the generated code.

Enabled C++11 in the expression parser. auto and
various other syntactic sugar work. Lambdas do
not due to some problems relocating code containing
lambdas. Rvalue references work when returned from
expressions, but need more testing.

generation of implicit floating point instructions can be disable for ARM.

Warn about -Wno-foo where foo is an unknown warning option. This is helpful
for subtle misspellings such as -Wno-unused-command-line-arguments instead of
-Wno-unused-command-line-argument.
Also fix the diagnostic messages to properly handle -Wno- options. Previously,
the positive version was always emitted (i.e., -Wfoo was emitted for -Wno-foo).
