fe5c9cee80 [AArch64] Implement the isTruncateFree API. 
In AArch64 i64 to i32 truncate operation is a subregister access.

This allows more opportunities for LSR optmization to eliminate
variables of different types (i32 and i64).

e4b14ebcbd [DAGCombiner] DAG combine does not know how to combine indexed loads with 
sign/zero/any extensions. However a few places were not checking properly the
property of the load and were turning an indexed load into a regular extended
load. Therefore the indexed value was lost during the process and this was
triggering an assertion.

fb065a1669 Revert "Revert "YAMLIO: Encode ambiguous hex strings explicitly"" 
Don't quote octal compatible strings if they are only two wide, they
aren't ambiguous.

This reverts commit r205857 which reverted r205857.

aef1966ed6 obj2yaml: Don't crash if the characteristics field is zero 
obj2yaml would fail when seeing a Weak External auxiliary record with a
characteristics field holding zero instead of one of
IMAGE_WEAK_EXTERN_SEARCH_NOLIBRARY, IMAGE_WEAK_EXTERN_SEARCH_NOLIBRARY,
or IMAGE_WEAK_EXTERN_SEARCH_NOLIBRARY.

77f268945e [NVPTX] Add preliminary intrinsics and codegen support for textures/surfaces 
This commit adds intrinsics and codegen support for the surface read/write and texture read instructions that take an explicit sampler parameter. Codegen operates on image handles at the PTX level, but falls back to direct replacement of handles with kernel arguments if image handles are not enabled. Note that image handles are explicitly disabled for all target architectures in this change (to be enabled later).
