[Modules] Do not remove failed modules after the control block phase
Reading modules first reads each control block in the chain and then all
AST blocks.
The first phase is intended to find recoverable errors, eg. an out of
date or missing module. If any error occurs during this phase, it is
safe to remove all modules in the chain as no references to them will
exist.
While reading the AST blocks, however, various fields in ASTReader are
updated with references to the module. Removing modules at this point
can cause dangling pointers which can be accessed later. These would be
otherwise harmless, eg. a binary search over `GlobalSLocEntryMap` may
access a failed module that could error, but shouldn't crash. Do not
remove modules in this phase, regardless of failures.
Since this is the case, it also doesn't make sense to return OutOfDate
during this phase, so remove the two cases where this happens.
When they were originally added these checks would return a failure when
the serialized and current path didn't match up. That was updated to an
OutOfDate as it was found to be hit when using VFS and overriding the
umbrella. Later on the path was changed to instead be the name as
written in the module file, resolved using the serialized base
directory. At this point the check is really only comparing the name of
the umbrella and only works for frameworks since those don't include
`Headers/` in the name (which means the resolved path will never exist)
Given all that, it seems safe to ignore this case entirely for now.
This makes the handling of an umbrella header/directory the same as
regular headers, which also don't check for differences in the path
caused by VFS.

[libc++abi] Fix possible infinite loop in itanium demangler
A libfuzzer run has discovered some inputs for which the demangler does
not terminate. When minimized, it looks like this: _Zcv1BIRT_EIS1_E
Deciphered:
_Z
cv - conversion operator
* result type
1B - "B"
I - template args begin
R - reference type <.
T_ - forward template reference | *
E - template args end | |
| |
* parameter type | |
I - template args begin | |
S1_ - substitution #1 * <'
E - template args end
The reason is: template-parameter refs in conversion operator result type
create forward-references, while substitutions are instantly resolved via
back-references. Together these can create a reference loop. It causes an
infinite loop in ReferenceType::collapse().
I see three possible ways to avoid these loops:
1. check if resolving a forward reference creates a loop and reject the
invalid input (hard to traverse AST at this point)
2. check if a substitution contains a malicious forward reference and
reject the invalid input (hard to traverse AST at this point;
substitutions are quite common: may affect performance; hard to
clearly detect loops at this point)
3. detect loops in ReferenceType::collapse() (cannot reject the input)
This patch implements (3) as seemingly the least-impact change. As a
side effect, such invalid input strings are not rejected and produce
garbage, however there are already similar guards in
`if (Printing) return;` checks.

This reverts commit
797fe59e6b9512652c0ae5a6b69a3c6f5a573fcd.
The use of "EventType type : 3" is replicated for all Event structs and
therefore was still present. As a result this still caused failures on
older GCCs (9.2 or 8.3 or earlier).
The particular bot that was failing due to buggy GCC was fixed by
fef39cc472a773fae4761deaab1c701024ad13ec.
Therefore, no reason to keep the workaround around; revert it.

[flang] Fix regression from recent runtime input fix
A recent runtime I/O change[1] was meant to improve the handling of
input from external files missing a terminal newline on their last
records; the change was "triggered" by the wrong circumstances and
causing reads that should have pulled more data into the buffer to be
treated as EOFs. So fix that, and also don't retain input data
in the buffer once an input record has been finished unless it's
known that list-directed or NAMELIST input of a repeated input item
may need to backspace a non-positionable external unit to return
to the beginning of the repeated item.

[SCEVExpander] Stop hoisting IR when reusing phis
his is a fix for PR43678, and is an alternate patch to D105723.
The basic issue we're running into is that LSR + SCEVExpander are moving the very instruction whose operand we're in the process of expanding. This breaks the subtle and ill-documented invariant which let LSR work. (Full story can be found here: https://reviews.llvm.org/D105723#2878473)
Rather than attempting a fix, this change just removes the optimization entirely. The code is entirely untested, and removing it appears to have no impact I can find. This code was added back in 2014 by
1e12f8563d4b7 with a single test which does not seem to actually test the hoisting logic.
From a philosophical standpoint, it also seems very strange to have the expander implementing optimizations which should live in a dedicated transform pass.
