Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field.

When a target instruction wants to set target-specific flags, it should simply
set bits in the TSFlags bit vector defined in the Instruction TableGen class.

This works well because TableGen resolves member references late:

class I : Instruction {
  AddrMode AM = AddrModeNone;
  let TSFlags{3-0} = AM.Value;
}

let AM = AddrMode4 in
def ADD : I;

TSFlags gets the expected bits from AddrMode4 in this example.

add a new EmitInlineAsm function to asmprinter to handle inline asm.
If we have an MCAsmStreamer, we continue to emit asm textually,
otherwise we (currently) emit an error to errs and ignore it.

remove some extraneous casts

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100287 91177308-0d34-0410-b5e6-96231b3b80d8

require that the branch being controlled by the IV
exits the loop.  With this information we can guarantee
the iteration count of the loop is bounded by the
compare.  I think this xforms is finally safe now.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100285 91177308-0d34-0410-b5e6-96231b3b80d8

add integer overflow check for the fp induction variable
checker.  Amusingly, we already had tests that we should
have rejects because they would be miscompiled in the
testsuite.

The remaining issue with this is that we don't check that
the branch causes us to exit the loop if it fails, so we
don't actually know if we remain in bounds.

add a comment and fix some consistency issues, converting
to a signed vs unsigned value depending on the sign of the
constant fp means that we can't distinguish between a
truly negative number and a positive number so large the
32nd bit is set.  So, do don't this!

fix PR6761, a miscompilation due to the fp->int IV conversion
stuff.  More bugs remain though.

just eliminate the uitofp checks.  This code isn't doing
the required validity checks in the first place, and supporting
a condition large enough to require the 32'nd bit isn't worth it.
