[AIX] Generate unique module id based on Pid and timestamp A unique module id, which is a part of sinit and sterm function names, is necessary to be unique. However, `getUniqueModuleId` will fail if there is no strong external symbol within a module. We turn to use Pid and timestamp when this happens.

[AIX] Static init frontend recovery and backend support On the frontend side, this patch recovers AIX static init implementation to use the linkage type and function names Clang chooses for sinit related function. On the backend side, this patch sets correct linkage and function names on aliases created for sinit/sterm functions. Differential Revision: https://reviews.llvm.org/D84534

; FIXME: Adjust the comment after we use source file full path to generate unique
; module id instead.
; Use the Pid and timestamp to generate a unique module id when strong external
; symbols are not available in current module. The module id generated in this
; way is not reproducible. A function name sample would be:
; __sinit80000000_clangPidTime_119189_1597348415_0
; CHECK: .lglobl foo[DS]
; CHECK: .lglobl .foo
; CHECK: .csect foo[DS]
; CHECK-NEXT: __sinit80000000_clangPidTime_[[PID:[0-9]+]]_[[TIMESTAMP:[0-9]+]]_0:

; CHECK-NEXT: .__sinit80000000_clangPidTime_[[PID]]_[[TIMESTAMP]]_0:
