LinkerScript.cpp contains both the linker script processor and the
linker script parser. I put both into a single file, but the file grown
too large, so it's time to put them into two different files.

Summary:
For WinEH, We add a funclet bundle to a coro.end call, so that CoroSplit in LLVM can replace it with cleanup ret and cut the rest out.
For landing pad, we add a branch to resume block if coro.end returns true.

Fix a bug in ARC contract pass where an iterator that pointed to a
deleted instruction was dereferenced.
It appears that tryToContractReleaseIntoStoreStrong was incorrectly
assuming that a call to objc_retain would not immediately follow a call
to objc_release.

Summary:
This adds support for reporting multiple errors in a single invocation of lld-link. The limit defaults to 20 and can be changed with the /ERRORLIMIT command line parameter, or set to unlimited by passing a value of 0.
This is a new attempt after r295507, which was reverted because opening files raced with exiting early, causing the test to be flaky. This version avoids the race by exiting before calling enqueuePath.

Before r294774, there was a problem when lowering broadcasts to use
128-bit subvectors.
When we looked through a bitcast to find the broadcast input, we'd keep
using the original type, so you'd end up with things like:
(v8f32 (broadcast
(v4f32 (extract_subvector
(v8i32 V),
...))
))
r294774 fixed it to always emit subvectors with the scalar type of the
original source.
It also introduced some asserts, to check that we use scalars with
the same size, and vectors with the same number of elements.
The scalar size equality is checked earlier when looking through bitcasts,
and is a useful assert.
However, the number of elements don't have to be identical: we're always
going to extract a 128-bit subvector, and we can have different size
inputs if we looked through a concat_vector to find a 256-bit source.
Relax the overzealous assert.
Replace it with a check of the original source vector being 256 or 512
bits. If it's 128 bits, we can't extract_subvector from it.
Fixes PR32371.

This caused a failure in the test case:
functionalities/breakpoint/objc/TestObjCBreakpoints.py
When we are parsing up names we stick interesting parts of the names
in various buckets, one of which is the ObjC selector bucket. The new
C++ name parser must be interfering with this process somehow.

Decouple this setting from EnableIRPA.
To support function calls on AMDGPU, it is necessary to
report the global register usage throughout the kernel's
call graph, so callees need to be handled first.

stores with some fixes.
Summary:
This enables us to cache the clobbering access for stores, despite the
fact that we can't rewrite the use-def chains themselves.
Early testing shows that, after this change, for larger testcases, it
will be a significant net positive (memory and time) to remove the
walker caching.

Set correct default flags and section type based on its name for .text,
.data, .bss, .init_array, .fini_array, .preinit_array, .tdata, and .tbss
and support section name suffixes for .data.*, .rodata.*, .text.*,
.bss.*, .tdata.* and .tbss.* which matches the behavior of GAS.

This improves upon r246462: that prevented FMOVs from being emitted
for the cross-class INSERT_SUBREGs by disabling the formation of
INSERT_SUBREGs of LOAD. But the ld1.s that we started selecting
caused us to introduce partial dependencies on the vector register.
Avoid that by using SCALAR_TO_VECTOR: it's a first-class citizen that
is folded away by many patterns, including the scalar LDRS that we
want in this case.
Credit goes to Adam for finding the issue!

This patch adds the option -print-resource-dir. It simply
prints the resource directory. This information will eventually
be used in compiler-rt to setup COMPILER_RT_LIBRARY_INSTALL_DIR.

This works with a regular shell since the kernel can keep track of a
deleted cwd. Since we just keep a path string, the following
subprocess invocations fail.
I think this would also fail on windows.

This adds the new pragma and the first variant, contract(on/off/fast).
The pragma has the same block scope rules as STDC FP_CONTRACT, i.e. it can be
placed at the beginning of a compound statement or at file scope.
Similarly to STDC FP_CONTRACT there is no need to use attributes. First an
annotate token is inserted with the parsed details of the pragma. Then the
annotate token is parsed in the proper contexts and the Sema is updated with
the corresponding FPOptions using the shared ActOn function with STDC
FP_CONTRACT.
After this the FPOptions from the Sema is propagated into the AST expression
nodes. There is no change here.
I was going to add a 'default' option besides 'on/off/fast' similar to STDC
FP_CONTRACT but then decided against it. I think that we'd have to make option
uppercase then to avoid using 'default' the keyword. Also because of the
scoped activation of pragma I am not sure there is really a need a for this.

With this, FMF(contract) becomes an alternative way to express the request to
contract.
These are currently only propagated for FMul, FAdd and FSub. The rest will be
added as more FMFs are hooked up for this.
