Recommit: Compress formatting of array type names (int [4] -> int[4])
Based on post-commit review discussion on

Other uses of forcing HasEmptyPlaceHolder to false seem OK to me -
they're all around pointer/reference types where the pointer/reference
token will appear at the rightmost side of the left side of the type
name, so they make nested types (eg: the "int" in "int *") behave as
though there is a non-empty placeholder (because the "*" is essentially
the placeholder as far as the "int" is concerned).
This was originally committed in 277623f4d5a672d707390e2c3eaf30a9eb4b075c
Reverted in f9ad1d1c775a8e264bebc15d75e0c6e5c20eefc7 due to breakages
outside of clang - lldb seems to have some strange/strong dependence on
"char [N]" versus "char[N]" when printing strings (not due to that name
appearing in DWARF, but probably due to using clang to stringify type
names) that'll need to be addressed, plus a few other odds and ends in
other subprojects (clang-tools-extra, compiler-rt, etc).

Revert "Compress formatting of array type names (int [4] -> int[4])"
Looks like lldb has some issues with this - somehow it causes lldb to
treat a "char[N]" type as an array of chars (prints them out
individually) but a "char [N]" is printed as a string. (even though the
DWARF doesn't have this string in it - it's something to do with the
string lldb generates for itself using clang)
This reverts commit 277623f4d5a672d707390e2c3eaf30a9eb4b075c.

[Analyzer] Allow creation of stack frame for functions without definition
Retrieving the parameter location of functions was disabled because it
may causes crashes due to the fact that functions may have multiple
declarations and without definition it is difficult to ensure that
always the same declration is used. Now parameters are stored in
`ParamRegions` which are independent of the declaration of the function,
therefore the same parameters always have the same regions,
independently of the function declaration used actually. This allows us
to remove the limitation described above.

[Analyzer] [NFC] Parameter Regions
Currently, parameters of functions without their definition present cannot
be represented as regions because it would be difficult to ensure that the
same declaration is used in every case. To overcome this, we split
`VarRegion` to two subclasses: `NonParamVarRegion` and `ParamVarRegion`.
The latter does not store the `Decl` of the parameter variable. Instead it
stores the index of the parameter which enables retrieving the actual
`Decl` every time using the function declaration of the stack frame. To
achieve this we also removed storing of `Decl` from `DeclRegion` and made
`getDecl()` pure virtual. The individual `Decl`s are stored in the
appropriate subclasses, such as `FieldRegion`, `ObjCIvarRegion` and the
newly introduced `NonParamVarRegion`.

[Analyzer] SValBuilder Comparison Rearrangement (with Restrictions and Analyzer Option)
Since the range-based constraint manager (default) is weak in handling comparisons where symbols are on both s
[Analyzer] SValBuilder Comparison Rearrangement (with Restrictions and Analyzer Option)
Since the range-based constraint manager (default) is weak in handling comparisons where symbols are on both sides it is wise to rearrange them to have symbols only on the left side. Thus e.g. A + n >= B + m becomes A - B >= m - n which enables the constraint manager to store a range m - n .. MAX_VALUE for the symbolic expression A - B. This can be used later to check whether e.g. A + k == B + l can be true, which is also rearranged to A - B == l - k so the constraint manager can check whether l - k is in the range (thus greater than or equal to m - n).
The restriction in this version is the the rearrangement happens only if both the symbols and the concrete integers are within the range [min/4 .. max/4] where min and max are the minimal and maximal values of their type.
The rearrangement is not enabled by default. It has to be enabled by using -analyzer-config aggressive-relational-comparison-simplification=true.
Co-author of this patch is Artem Dergachev (NoQ).

C++ object-type return values of conservatively evaluated functions are now

function creates a region that represents the temporary object and will later
be used for destruction or materialization, invalidates it, and returns the
invalidated compound value of the object.

DR1213: element access on an array xvalue or prvalue produces an xvalue. In the
latter case, a temporary array object is materialized, and can be
lifetime-extended by binding a reference to the member access. Likewise, in an
array-to-pointer decay, an rvalue array is materialized before being converted
into a pointer.
This caused IR generation to stop treating file-scope array compound literals
as having static storage duration in some cases in C++; that has been rectified
by modeling such a compound literal as an lvalue. This also improves clang's
compatibility with GCC for those cases.
