Summary:
Java and JavaScript support annotations and decorators, respectively, that use a leading "@" token. clang-format currently detects this as an Objective-C construct and applies special formatting, for example no whitespace around "=" operators. This change disables the distinction for Java and JavaScript, which leads to normal formatting of single line annotated and initialized properties.
Before:
class X {
@foo() bar=false;
}
After:
class X {
@foo() bar = false;
}

Summary: In JavaScript/TypeScript, class member definitions that use modifiers can be subject to Automatic Semicolon Insertion (ASI). For example, "class X { get \n foo }" defines a property called "get" and a property called "foo", both with no type annotation. This change prevents wrapping after the modifier keywords (visibility modifiers, static, get and set) to prevent accidental ASI.

Removed micro mips register classes for gp initialization because gp initialization uses pure mips64 instruction. Even when compiling for micro mips, gp initialization can be done with pure mips64 instructions.

r299766 contained a "conditional move or jump depends on uninitialized value"
fault, identified by valgrind. This occurred as MipsFastISel::finishCall(..)
used CCState over MipsCCState. The latter is required for the TableGen'd calling
convention logic due to reliance on pre-analyzing type information to lower call
results/returns of vectors correctly.
This change modifies the MipsCC AnalyzeCallResult to be useful with both the
SelectionDAG and FastISel lowering logic.

gnu ld description of option is:
--defsym=symbol=expression
Create a global symbol in the output file, containing the absolute address given
by expression. You may use this option as many times as necessary to define multiple
symbols in the command line. A limited form of arithmetic is supported for the
expression in this context: you may give a hexadecimal constant or the name of an
existing symbol, or use "+" and "-" to add or subtract hexadecimal constants or
symbols. If you need more elaborate expressions, consider using the linker command
language from a script. Note: there should be no white space between symbol,
the equals sign ("="), and expression.
In compare with D32082, this patch does not support math expressions and absolute
symbols. It implemented via code similar to --wrap. That covers 1 of 3 possible
--defsym cases.

Summary:
This patch introduces new SB APIs for tracing support
inside LLDB. The idea is to gather trace data from
LLDB and provide it through this APIs to external
tools integrating with LLDB. These tools will be
responsible for interpreting and presenting the
trace data to their users.
The patch implements the following new SB APIs ->
-> StartTrace - starts tracing with given parameters
-> StopTrace - stops tracing.
-> GetTraceData - read the trace data .
-> GetMetaData - read the meta data assosciated with the trace.
-> GetTraceConfig - read the trace configuration
Tracing is associated with a user_id that is returned
by the StartTrace API and this id needs to be used
for accessing the trace data and also Stopping
the trace. The user_id itself may map to tracing
the complete process or just an individual thread.
The APIs require an additional thread parameter
when the user of these APIs wishes to perform
thread specific manipulations on the tracing instances.
The patch also includes the corresponding
python wrappers for the C++ based APIs.

the renaming of CtxI to be consistent, etc.
This should be NFC.

It's possible to determine the alignment of an alloca at compile-time.
Use this information to skip emitting some runtime alignment checks.
Testing: check-clang, check-ubsan.
This significantly reduces the amount of alignment checks we emit when
compiling X86ISelLowering.cpp. Here are the numbers from patched/unpatched
clangs based on r301361.
------------------------------------------
| Setup | # of alignment checks |

| unpatched, -O0 | 47195 |
| patched, -O0 | 30876 | (-34.6%)

This change restores pre-r301225 behavior, where linker GC compatible global
instrumentation was used on COFF targets disregarding -f(no-)data-sections and/or
/Gw flags.
This instrumentation puts each global in a COMDAT with an ASan descriptor for that global.
It effectively enables -fdata-sections, but limits it to ASan-instrumented globals.

The order in which GCOV file info is printed depends on the string hash
function. This makes some GCOV tests brittle, because the tests must be
updated whenever the hash function changes.
Sort the filenames before printing out the file info to solve the
problem. This should be relatively cheap.

Summary:
When running run-clang-tidy.py with -fix it tries to apply found replacements at the end.
If there are errors running clang-apply-replacements, the script currently crashes or displays no error at all.
This patch checks for errors running clang-apply-replacements the same way clang-tidy binary is handled.
Another option would be probably checking for clang-apply-replacements (when -fix is passed) even before running clang-tidy.
