allow it to complete types on behalf of any AST context
(including the "scratch" AST context associated with
the target), I scrapped its role as intermediary between
the Clang parser and ClangExpressionDeclMap, and instead
made ClangExpressionDeclMap inherit from ClangASTSource.
After this, I will migrate the functions that complete
types and perform namespace lookups from
ClangExpressionDeclMap to ClangASTSource. Ultimately
ClangExpressionDeclMap's only responsiblity will be to
look up variables and ensure that they are materialized
and dematerialized correctly.

Introduce a FILE_SORTED_DECLS [de]serialization record that contains
a file sorted array of file-level DeclIDs in a PCH/Module.
The rationale is to allow "targeted" deserialization of decls inside
a range of a source file.
Cocoa PCH increased by 0.8%
Difference of creation time for Cocoa PCH is below the noise level.

constexpr function arguments outside of their function (passing or returning
them by reference) does not work correctly yet.
Calling constexpr function templates does not work yet, since the bodies are not
instantiated until the end of the translation unit.

For example,
On ARM, "mov r3, #-3" is an alias for "mvn r3, #2", so we want to use a
matcher pattern that handles the bitwise negation when mapping to t2MVNi.

things like:
(lldb) x/32xb 0x1000
"x" is an alias to "memory read", so this will actually turn into:
(lldb) memory read --gdb-format=32xb 0x1000
This applies to all commands, so the GDB formats will work with "register read",
"frame variable", "target variable" and others. All commands that can accept
formats, counts and sizes have been modified to support the "--gdb-format"
option.

Spotted by my super-optimizer in 186.crafty and 450.soplex. We really
need a proper infrastructure for handling generalizations of this kind
of thing (which occur a lot), however this case is so simple that I decided
to go ahead and implement it directly.

fixes: Use a separate register, instead of SP, as the
calling-convention resource, to avoid spurious conflicts with
actual uses of SP. Also, fix unscheduling of calling sequences,
which can be triggered by pseudo-two-address dependencies.

are present in all the necessary places:
In constant expression evaluation, evaluate lvalues as lvalues and rvalues as
rvalues. Remove special case for caching reference initialization and fix a
cyclic initialization crash in the process.

Outside an IT block, "add r3, #2" should select a 32-bit wide encoding
rather than generating an error indicating the 16-bit encoding is only
legal in an IT block (outside, the 'S' suffic is required for the 16-bit
encoding).

If the register class in the source alias is a subclass of the register class
of the actual instruction, the alias can still match OK since the constraints
are strictly a subset of what the instruction can actually handle.
