This fixes <rdar://problem/8869639>. I also filed PR9184 on doing this sort of
thing automatically, but it seems easier to just change the ordering of the
passes if this is the only case.

This is a hack because we really should only search in the 'include/clang/StaticAnalyzer' directory
if we are in 'lib/StaticAnalyzer'. My CMake knowledge is limited, so I appeal to anyone with
more expertise.

When matching operands for a candidate opcode match in the auto-generated
AsmMatcher, check each operand against the expected operand match class.
Previously, operands were classified independently of the opcode being
handled, which led to difficulties when operand match classes were
more complicated than simple subclass relationships.

of the CPSR during the course of executing an opcode, and modified SelectInstrSet()
to update this variable instead of the original m_inst_cpsr, which should be
the cached copy of the CPSR at the beginning of executing the opcode.

name of a path, after resolving symbolic links and eliminating excess
path elements such as "foo/../" and "./".
This routine still needs a Windows implementation, but I don't have a
Windows machine available. Help? Please?

Now, Syntax is only used as a tie-breaker if the Arch
matches. Previously, a request for x86_64 disassembler followed by the
i386 disassembler in a single process would return the cached x86_64
disassembler. Fixes <rdar://problem/8958982>

module's AST context. Prior to this fix, with gcc binaries, we end up with
a full class definition for any used classes in each compile unit due to the
one definition rule. This would result in us making N copies of class T, where
N is the number of compile units that use class T, in the module AST. When
an expression would then try and use any types that were duplicated, it would
quickly confuse clang and make expression evaluation fail due to all of the
duplicate types that got copied over. This is now fixed by making a map of
types in the DWARF that maps type names to a collection of types + declaration
(file + line number) + DIE. Then later when we find a type we look in this
module map and find any already cached types that we can just use.

versions of creation functions. Eventually, the "insertion point" versions
of these should just be removed, we do have IRBuilder afterall.
Do a massive rewrite of much of pattern match. It is now shorter and less
redundant and has several other widgets I will be using in other patches.
Among other changes, m_Div is renamed to m_IDiv (since it only matches
integer divides) and m_Shift is gone (it used to match all binops!!) and
we now have m_LogicalShift for the one client to use.
Enhance IRBuilder to have "isExact" arguments to things like CreateUDiv
and reduce redundancy within IRbuilder by having these methods chain to
each other more instead of duplicating code.

an annoyance of mine when working on tests: if the input .ll file
is broken, opt outputs an error and generates an empty file. FileCheck
then emits its "ooh I couldn't find the first CHECK line, scanning
from ..." which obfuscates the actual problem.
