Change math intrinsic attributes from readonly to readnone. These
...
are operations that do not access memory but may be sensitive
to floating-point environment changes. LLVM does not attempt
to model FP environment changes, so this was unnecessarily conservative
and was getting on the way of some optimizations, in particular
SLP vectorization.

[-Wunreachable-code] Handle idiomatic do...while() with an uninteresting condition.

Sometimes do..while() is used to create a scope that can be left early.

On cores without fpcvt support, we cannot promote int_to_fp i1 operations,

Always print the implicit .text at the start of an asm file.
...
Before llvm-mc would print it, but llc was assuming that it would produce
another section changing directive before one was needed. That assumption is
false with inline asm.
Fixes PR19049.
Another option would be to always create the section, but in the asm printer
avoid printing sections changes during initialization. That would work, but
* We do use the fact that llvm-mc prints it in testing. The tests can be changed
if needed.
* A quick poll on IRC suggest that most developers prefer the implicit .text to
be printed.
