08533f8b86 Revert "[CGP] Add generic TargetLowering::shouldAlignPointerArgs() implementation" 
These commits are causing a test-suite build failure on AIX. Revert for now for time to investigate.
https://lab.llvm.org/buildbot/#/builders/214/builds/5779/steps/9/logs/stdio

This reverts commit bd87a2449da0c82e63cebdf9c131c54a5472e3a7 and 4c72266830ffa332ebb7cf1d3bbd6c56d001fa0f.

bd87a2449d [CGP] Add generic TargetLowering::shouldAlignPointerArgs() implementation 
This function was added for ARM targets, but aligning global/stack pointer
arguments passed to memcpy/memmove/memset can improve code size and
performance for all targets that don't have fast unaligned accesses.
This adds a generic implementation that adjusts the alignment to pointer
size if unaligned accesses are slow.
Review D134168 suggests that this significantly improves performance on
synthetic benchmarks such as Dhrystone on RV32 as it avoids memcpy() calls.

122b0220fd [WebAssembly] Remove datalayout strings from llc tests 
The data layout strings do not have any effect on llc tests and will become
misleadingly out of date as we continue to update the canonical data layout, so
remove them from the tests.

16d83c395a [WebAssembly] Added 64-bit memory.grow/size/copy/fill 
This covers both the existing memory functions as well as the new bulk memory proposal.
Added new test files since changes where also required in the inputs.

Also removes unused init/drop intrinsics rather than trying to make them work for 64-bit.
