Add support for float-to-long in the optimizing compiler.
- Add support for the float-to-long Dex instruction in the
optimizing compiler.
- Add a Dex PC field to art::HTypeConversion to allow the
x86 and ARM code generators to produce runtime calls.
- Instruct art::CodeGenerator::RecordPcInfo not to record
PC information for HTypeConversion instructions.
- Add S0 to the list of ARM FPU parameter registers.
- Have art::x86_64::X86_64Assembler::cvttss2si work with
64-bit operands.
- Generate x86, x86-64 and ARM (but not ARM64) code for
float to long HTypeConversion nodes.
- Add related tests to test/422-type-conversion.
