Sort all of Clang's files under 'lib', and fix up the broken headers
...
uncovered.
This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.
I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

If the range in a for range statement doesn't have a viable begin/end function,
...
but can be dereferenced to form an expression which does have viable begin/end
functions, then typo-correct the range, even if something else goes wrong with
the statement (such as inaccessible begin/end or the wrong type of loop
variable).
In order to ensure we recover correctly and produce any followup diagnostics in
this case, redo semantic analysis on the for-range statement outside of the
diagnostic trap, after issuing the typo-correction.

Better diagnostics for range-based for loops with bad range types.
...
The old error message stating that 'begin' was an undeclared identifier
is replaced with a new message explaining that the error is in the range
expression, along with which of the begin() and end() functions was
problematic if relevant.
Additionally, if the range was a pointer type or defines operator*,
attempt to dereference the range, and offer a FixIt if the modified range
works.

[ms-inline asm] Have patchMSAsmStrings() return a vector or AsmStrings.

The AsmParser expects a single asm instruction, but valid ms-style inline asm
statements may contain multiple instructions.
This happens with asm blocks
__asm {
mov ebx, eax
mov ecx, ebx
}
or when multiple asm statements are adjacent to one another
__asm mov ebx, eax
__asm mov ecx, ebx
and
__asm mov ebx, eax __asm mov ecx, ebx
Currently, asm blocks are not properly handled.
