ART: Address issues with kIntrinsicMinMaxDouble for x86

This patch fixes the following issues:
- Makes sure that invoke-static/range is considered for analysis
path that decides whether base of code register is needed.
- Invalidates the code pointer register in intrinsic implementations
of min/max for FP since generated code has diamond shape and Quick
does not correctly handle control flow merges.
- Reverts the clobbering of base of code register from constant
loading path since it reduces performance in linear code that
needs the register.
- Ensures that no assumption is made on whether base of code register
exists in cases like 64-bit where rip register may be used.
