…wn-sgx target.

1. We support synchronization across multiple threads via functions
exposed by Rust STD lib for this target instead of libunwind.
2. We have implemented dl_iterate_phdr implementation that provides
eh_frm_hdr and text sections for the application running in the enclave.
3. Changes done to support error logging for this target.

[PowerPC][NFC]Remove sms-simple.ll test temporarily.

Looks like a MachinePipeliner algorithm problem found by
sanitizer-x86_64-linux-fast.
I will backout this test first while investigating the problem to
unblock buildbot.

[IR] Store attributes that are available "somewhere" (NFC)
9a334a4 
I noticed that for some benchmarks we spend quite a bit of time
inside AttributeList::hasAttrSomewhere(), mainly when checking
for the "returned" attribute. Most of the time the attribute will
not be present, in which case this function has to walk through
the whole attribute list and check for the attribute at each index.

This patch adds a cache of all "available somewhere" attributes
inside AttributeListImpl. This makes the structure 12 bytes larger,
but I don't think that's problematic, as attribute lists are uniqued.
Compile-time in terms of instructions retired improves by 0.4% on
average, but >1% for sqlite.

[SelectionDAG] Use int64_t to store the integer power of llvm.powi
8f966ce 
https://llvm.org/docs/LangRef.html#llvm-powi-intrinsic
The max length of the integer power of `llvm.powi` intrinsic is 32, and
the value can be negative. If we use `int32_t` to store this value, `-Val`
will underflow when it is `INT32_MIN`

The issue was reported in D149033.
