[WPD] Fix incorrect devirtualization after indirect call promotion
Summary:
Add a dominance check to ensure that the possible devirtualizable
call is actually dominated by the type test/checked load intrinsic being
analyzed. With PGO, after indirect call promotion is performed during
the compile step, followed by inlining, we may have a type test in the
promoted and inlined sequence that allows an indirect call in that
sequence to be devirtualized. That indirect call (inserted by inlining
after promotion) will share the same vtable pointer as the fallback
indirect call that cannot be devirtualized.
Before this patch the code was incorrectly devirtualizing the fallback
indirect call.
See the new test and the example described there for more details.

[IslAst] Fix InParallelFor nesting.
IslAst could mark two nested outer loops as "OutermostParallel". It
caused that the code generator tried to OpenMP-parallelize both loops,
which it is not prepared loop.
It was because the recursive AST build algorithm managed a flag
"InParallelFor" to ensure that no nested loop is also marked as
"OutermostParallel". Unfortunatetly the same flag was used by nodes
marked as SIMD, and reset to false after the SIMD node. Since loops can
be marked as SIMD inside "OutermostParallel" loops, the recursive
algorithm again tried to mark loops as "OutermostParellel" although
still nested inside another "OutermostParallel" loop.
The fix exposed another bug: The function "astScheduleDimIsParallel" was
only called when a loop was potentially "OutermostParallel" or
"InnermostParallel", but as a side-effect also determines the minimum
dependence distance. Hence, changing when we need to know whether a loop
is "OutermostParallel" also changed which loop was annotated with
"#pragma minimal dependence distance".
Moreover, some complex condition linked with "InParallelFor" determined
whether a loop should be an "InnermostParallel" loop. It missed some
situations where it would not use mark as such although being inside an
SIMD mark node, and therefore not be annotated using "#pragma simd".
The changes in particular:
1. Split the "InParallelFor" flag into an "InParallelFor" and an
"InSIMD" flag.
2. Unconditionally call "astScheduleDimIsParallel" for its side-effects
and store the result in "InParallel" for later use.
3. Simplify the condition when a loop is "InnermostParallel".

- stripRegisterPrefix() - this just removes the letter prefixes from registers
for the InstrPrinter and AsmPrinter. This patch provides this as a static
member of PPCRegisterInfo
- Handling of PPCII::UseVSXReg - there are 3 places where we do something
special for instructions with that flag set. Each of those places does its
own checking of this flag and implements code customization. Any changes to
how we print/encode VSX/VMX registers require modifying all 3 places. This

The `ClangUserExpression::GetLanguageForExpr` method is currently a big
source of sadness, as it's name implies that it's an accessor method, but it actually
is also initializing some variables that we need for parsing. This caused that we
currently call this getter just for it's side effects while ignoring it's return value,
which is confusing for the reader.
This patch renames it to `UpdateLanguageForExpr` and merges all calls to the
method into a single call in `ClangUserExpression::PrepareForParsing` (as calling
this method is anyway mandatory for parsing to succeed)
While looking at the code, I also found that we actually have two language
variables in this class hierarchy. The normal `Language` from the UserExpression
class and the `LanguageForExpr` that we implemented in this subclass. Both
don't seem to actually contain the same value, so we probably should look at this
next.

sancov.py relies on objdump -d to obtain the number of instrumented PCs.
The i386 %dynamiclib will now include .plt entries that are not recognized by objdump,
"sancov.py: found 0 instrumented PCs in *.so",
causing AddressSanitizer-i386-linux to fail.
Change it back to x86-target-arch after %sancov switches to a more robust approach.
