[NewPM][Inliner] Make inlined calls to functions in same SCC as callee exponentially expensive
Introduce a new attribute "function-inline-cost-multiplier" which
multiplies the inline cost of a call site (or all calls to a callee) by
the multiplier.
When processing the list of calls created by inlining, check each call
to see if the new call's callee is in the same SCC as the original
callee. If so, set the "function-inline-cost-multiplier" attribute of
the new call site to double the original call site's attribute value.
This does not happen when the original call site is intra-SCC.
This is an alternative to D120584, which marks the call sites as
noinline.
Hopefully fixes PR45253.

Add JSON output option to llvm-remark-size-diff
This adds JSON output to llvm-remark-size-diff.
The goal here is to make it easy for external tools to consume output from
llvm-remark-size-diff. These tools could be used for automated size analysis.
(E.g. in CI).
To specify JSON output, use `--report_style=json`. JSON output can be
pretty-printed via `--pretty`.
With automation in mind, the schema looks like this:
```
"Files": {
"A": <filename_a>
"B": <filename_b>
},
"InBoth": [
{
"FunctionName": <function name>,
"InstCount": [
<count_in_a>,
<count_in_b>
],
"StackSize": [
<count_in_a>,
<count_in_b>
]
},
...
]
"OnlyInA": [
{
"FunctionName": <function name>,
"InstCount": [
<count_in_a>,
0
],
"StackSize": [
<count_in_a>,
0
]
},
...

"OnlyInB": [
{
"FunctionName": <function name>,
"InstCount": [
0,
<count_in_b>
],
"StackSize": [
0,
<count_in_b>
]
},
...
]
```
A few notes:
- Filenames are included, because tools may want to combine many outputs
together in some way (a big JSON file, a big CSV, or something.)
- Counts are represented as [a, b] so that a diff can be calculated via b - a.
The original counts may be useful for size analysis (e.g. was this function
extremely large before?) and so both are preserved.
- `OnlyInA` and `OnlyInB` have a 0 for one of the counts always. This is to
make it easier for tools to share code between `OnlyInA`, `OnlyInB`, and
`InBoth`.

[clang][debug] port clang-cl /JMC flag to ELF
The motivation is to enable the MSVC-style JMC instrumentation usable by a ELF-based
debugger. Since there is no prior experience implementing JMC feature for ELF-based
debugger, it might be better to just reuse existing MSVC-style JMC instrumentation.
For debuggers that support both ELF&COFF (like lldb), the JMC implementation might
be shared between ELF&COFF. If this is found to inadequate, it is pretty low-cost
switching to alternatives.
Implementation:
- The '-fjmc' is already a driver and cc1 flag. Wire it up for ELF in the driver.
- Refactor the JMC instrumentation pass a little bit.
- The ELF handling is different from MSVC in two places:
* the flag section name is ".just.my.code" instead of ".msvcjmc"
* the way default function is provided: MSVC uses /alternatename; ELF uses weak function.

[mlir][Vector] Improve default lowering of vector transpose operations
The default lowering of vector transpose operations generates a large sequence of
scalar extract/insert operations, one pair for each scalar element in the input tensor.
In other words, the vector transpose is scalarized. However, there are transpose
patterns where one or more adjacent high-order dimensions are not transposed (for
example, in the transpose pattern [1, 0, 2, 3], dimensions 2 and 3 are not transposed).
This patch improves the lowering of those cases by not scalarizing them and extracting/
inserting a full n-D vector, where 'n' is the number of adjacent high-order dimensions
not being transposed. By doing so, we prevent the scalarization of the code and generate a
more performant vector version.
Paradoxically, this patch shouldn't improve the performance of transpose operations if
we are using LLVM. The LLVM pipeline is able to optimize away some of the extract/insert
operations and the SLP vectorizer is converting the scalar operations back to its vector
form. However, scalarizing a vector version of the code in MLIR and relying on the SLP
vectorizer to reconstruct the vector code again is highly undesirable for several reasons.
