x86: Handle TARGET_INDIRECT_BRANCH_REGISTER for -fno-plt
If TARGET_INDIRECT_BRANCH_REGISTER is true, indirect call and jump should
use register, not memory. Update Bs, Bw and Bz constraints to disable
indirect call over memmory if TARGET_INDIRECT_BRANCH_REGISTER true, change
x32 call over GOT slot to call over register and also disable sibcall
over memory.

* config/i386/constraints.md (Bs): Always disable if
TARGET_INDIRECT_BRANCH_REGISTER is true.
(Bw): Likewise.

call via register for x32 GOT slot call if
TARGET_INDIRECT_BRANCH_REGISTER is true.
* config/i386/i386-protos.h (ix86_nopic_noplt_attribute_p): New.
* config/i386/i386.cc (ix86_nopic_noplt_attribute_p): Make it
global.

memory for TARGET_INDIRECT_BRANCH_REGISTER.

Return false if both TARGET_INDIRECT_BRANCH_REGISTER and
ix86_nopic_noplt_attribute_p are true.
