On 32bits x86 Darwin, the register mappings for the eh_frane and

problem isn't target specific though, but it requires that the

Fix handling of double quotes (MI)
Summary:
* Clean CMICmdArgValString::Validate: now it's based on CMIUtilString::SplitConsiderQuotes method:
A bit of introduction:
# Command line is wrapped into CMICmdArgContext.
# CMICmdArgSet is a set of arguments to be parsed. This class contains CMICmdArgContext as a private member.
# MI command is class which is inhereted from CMICmdBase. It contains CMICmdArgSet as a private member.
When command is executed CMICmdBase::ParseArgs() is called. This method adds args for parsing using CMICmdArgSet::Add(). Then CMICmdBase::ParseValidateCmdOptions() is called, which calls CMICmdArgSet::Validate(). Then it gets a number of arguments (using SplitConsiderQuotes().array_length) and for each arguments registered in ParseArgs() tries to validate it using CMICmdArgValBase::Validate(). Every user commands parses this string again (first time it was made in SplitConsiderQuotes) and in case of CMICmdArgValString it was made incorrectly. It searches the first and last quotes (but it should be first and next after first). Besides, it was splitted into 4 cases.
I'm just using SplitConsiderQuotes directly, and I don't split them by hand again.
Actually, I think we should do so in every CMICmdArgVal_XXX::Validate() method.

libclc/math: Add cospi
Ported from the libclc/amd-builtins branch
v2: Rename sincos_f_piby4 to __libclc__sincosf_piby4
Add cospi(double) implementation instead of using llvm.cos
Notes:
The sincosD_piby4.h file is mostly the same as the builtin implementation
released by AMD. The inline attribute declaration is changed, and M_PI is
used instead of a constant double. Otherwise, the only difference is that
the header explicitly enables the fp64 pragma.

FileCheck: Add CHECK-SAME
Add `CHECK-SAME`, which requires that the pattern matches on the *same*
line as the previous `CHECK`/`CHECK-NEXT` -- in other words, no newline
is allowed in the skipped region. This is similar to `CHECK-NEXT`,
which requires exactly 1 newline in the skipped region.
My motivation is to simplify checking the long lines of LLVM assembly
for the new debug info hierarchy. This allows CHECK sequences like the
following:
CHECK: ![[REF]] = !SomeMDNode(
CHECK-SAME: file: ![[FILE:[0-9]+]]
CHECK-SAME: otherField: 93{{[,)]}}
which is equivalent to:
CHECK: ![[REF]] = !SomeMDNode({{.*}}file: ![[FILE:[0-9]+]]{{.*}}otherField: 93{{[,)]}}
While this example just has two fields, many nodes in debug info have
more than that. `CHECK-SAME` will keep the logic easy to follow.
Morever, it enables interleaving `CHECK-NOT`s without allowing newlines.
Consider the following:
CHECK: ![[REF]] = !SomeMDNode(
CHECK-SAME: file: ![[FILE:[0-9]+]]
CHECK-NOT: unexpectedField:
CHECK-SAME: otherField: 93{{[,)]}}
CHECK-NOT: otherUnexpectedField:
CHECK-SAME: )
