add thiscall calling convention support
This support is needed for bindgen to work well on 32-bit Windows, and also enables people to begin experimenting with C++ FFI support on that platform.
Fixes #42044.

This converts all of borrowck's `mut` suggestions to a new
`mc::ImmutabilityBlame` API instead of the current mix of various hacks.
Fixes #35937.
Fixes #40823.

Tracking issue: https://github.com/rust-lang/rust/issues/40180
This calling convention can be used for definining interrupt handlers on
32-bit and 64-bit x86 targets. The compiler then uses `iret` instead of
`ret` for returning and ensures that all registers are restored to their
original values.
Usage:
```
extern "x86-interrupt" fn handler(stack_frame: &ExceptionStackFrame) {…}
```
for interrupts and exceptions without error code and
```
extern "x86-interrupt" fn page_fault_handler(stack_frame: &ExceptionStackFrame,
error_code: u64) {…}
```
for exceptions that push an error code (e.g., page faults or general
protection faults). The programmer must ensure that the correct version
is used for each interrupt.
For more details see the [LLVM PR][1] and the corresponding [proposal][2].

This calling convention is used to define interrup handlers on MSP430
microcontrollers. Usage looks like this:
``` rust
#[no_mangle]
#[link_section = "__interrupt_vector_10"]
pub static TIM0_VECTOR: unsafe extern "msp430-interrupt" fn() = tim0;
unsafe extern "msp430-interrupt" fn tim0() {
P1OUT.write(0x00);
}
```
which generates the following assembly:
``` asm
Disassembly of section __interrupt_vector_10:
0000fff2 <TIM0_VECTOR>:
fff2: 10 c0 interrupt service routine at 0xc010
Disassembly of section .text:
0000c010 <_ZN3msp4tim017h3193b957fd6a4fd4E>:
c010: c2 43 21 00 mov.b #0, &0x0021 ;r3 As==00
c014: 00 13 reti
...
```

Given the following code:
```rust
struct Foo<T: Clone>(T);
use std::ops::Add;
impl<T: Clone, Add> Add for Foo<T> {
type Output = usize;
fn add(self, rhs: Self) -> Self::Output {
unimplemented!();
}
}
```
present the following output:
```nocode
error[E0404]: `Add` is not a trait
--> file3.rs:5:21
|
5 | impl<T: Clone, Add> Add for Okok<T> {
| --- ^^^ expected trait, found type parameter
| |
| type parameter defined here
```
|

in non-codegen tests. Remove false positive in a test that relied on the exact formatting of an error string and rewrite the sysv64 register allocation test at it was triggering undefined behaviour
