Generate compact unwind encoding from CFI directives.
...
We used to generate the compact unwind encoding from the machine
instructions. However, this had the problem that if the user used `-save-temps'
or compiled their hand-written `.s' file (with CFI directives), we wouldn't
generate the compact unwind encoding.
Move the algorithm that generates the compact unwind encoding into the
MCAsmBackend. This way we can generate the encoding whether the code is from a
`.ll' or `.s' file.

precision loads and stores as well as reg+imm double precision loads and stores.

precision stores and loads being emitted to spill and restore 64-bit FP registers.

vptr_update.ll when struct-path tbaa is on by default.
